A LETTER FROM THE CEO OF DREYFUS

Dear Shareholder:

We are pleased to present this annual report for Dreyfus Municipal Bond Opportunity Fund, covering the 12-month period from May 1, 2016 through April 30, 2017. For information about how the fund performed during the reporting period, as well as general market perspectives, we provide a Discussion of Fund Performance on the pages that follow.

Stocks advanced solidly over the past year while bonds produced mixed returns in response to various economic and political developments. Equities began the reporting period in the midst of a sustained rebound from previous weakness as global economic data improved, commodity prices recovered, and U.S. monetary policymakers delayed additional rate hikes. After a bout of volatility in June stemming from the United Kingdom’s referendum to leave the European Union, stocks generally continued to climb over the summer. The unexpected outcome of U.S. elections in early November sent stocks sharply higher in anticipation of new fiscal, regulatory, and tax policies. Generally strong economic data and corporate earnings continued to support stock prices over the first four months of 2017.

In the bond market, yields of high-quality government bonds declined toward historical lows early in the reporting period due to robust investor demand for current income, but yields subsequently moved higher in response to two short-term interest-rate hikes and rising longer-term rates. In contrast, lower-rated corporate-backed bonds generally fared well in anticipation of a more business-friendly market environment.

Some asset classes and industry groups seem likely to continue to benefit from a changing economic and geopolitical landscape, while others probably will face challenges as conditions evolve. Consequently, selectivity seems likely to be an important determinant of investment success in the months ahead. As always, we encourage you to discuss the implications of our observations with your financial advisor.

Thank you for your continued confidence and support.

Sincerely,

Mark D. Santero
Chief Executive Officer
The Dreyfus Corporation

DISCUSSION OF FUND PERFORMANCE

For the period from May 1, 2016 through April 30, 2017, as provided by Daniel Rabasco and Jeffrey Burger, Portfolio Managers

Market and Fund Performance Overview

For the 12-month period ended April 30, 2017, Dreyfus Municipal Bond Opportunity Fund’s Class A shares produced a total return of -0.70%, Class C shares returned -1.45%, and Class Z shares returned -0.65%.¹ In comparison, the Bloomberg Barclays U.S. Municipal Bond Index (the “Index”), the fund’s benchmark index, achieved a total return of 0.14% for the same period.² As of August 31, 2016, Class I and Class Y shares were added as new share classes of the fund. From their inception on August 31, 2016 through April 30, 2017, the fund’s Class I shares produced a total return of -2.56%, and Class Y shares returned -2.87%.

The Index generally produced flat returns during the reporting period amid rising interest rates, changing supply-and-demand dynamics, and political uncertainty. The fund lagged its benchmark, mainly due to its relatively long average duration in the rising interest-rate environment.

The Fund’s Investment Approach

The fund seeks to maximize current income from federal income tax to the extent consistent with the preservation of capital. To pursue its goal, the fund normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in municipal bonds that provide income exempt from federal income tax. Typically, the fund invests substantially all of its assets in such municipal bonds. The fund invests at least 70% of its assets in municipal bonds rated, at the time of purchase, investment grade (Baa/BBB or higher) or the unrated equivalent as determined by The Dreyfus Corporation (“Dreyfus”). For additional yield, the fund may invest up to 30% of its assets in municipal bonds rated below investment grade (“high yield” or “junk” bonds) or the unrated equivalent as determined by Dreyfus. The dollar-weighted average maturity of the fund’s portfolio normally exceeds ten years, but the fund may invest without regard to maturity or duration.

In managing the fund, we focus on identifying undervalued sectors and securities, and we minimize the use of interest-rate forecasting. We select municipal bonds using fundamental credit analysis to estimate the relative value of various sectors and securities, and to exploit pricing inefficiencies in the municipal bond market. In addition, we trade among the market’s various sectors—such as the pre-refunded, general obligation, and revenue sectors—based on their apparent relative values. The fund generally will invest simultaneously in several of these sectors.

Political and Economic Factors Weighed on Municipal Bonds

The reporting period began on a positive note amid rebounding commodity prices, subdued inflationary pressures, and indications that the Federal Reserve Board (the “Fed”) would delay expected short-term rate hikes. Income-oriented investors reached for competitive after-tax yields in the low-interest-rate environment, driving municipal bond prices higher.

The rally that persisted into summer 2016 abated heading into fall 2016 when issuers came to market with a flood of new municipal securities to take advantage of the then-low rate environment. Market declines became particularly severe in November 2016 after the unexpected election of a new presidential administration, which sparked uncertainty regarding potential changes in tax policy and fueled the possibility of fiscal stimulus. Moreover, rate hikes from the Fed in December 2016 and March 2017 put upward pressure on bond yields and downward pressure on prices. However, municipal bonds recouped some of the previous losses as valuations became more attractive and supply-and-demand imbalances moderated.

3

DISCUSSION OF FUND PERFORMANCE (continued)

Although the rate of positive growth in state tax revenues has moderated, and several states are facing pressure from underfunded pension systems, credit conditions remained sound for most municipal bond issuers.

Long Duration Posture Dampened Fund Results

The fund’s performance during the reporting period was undermined by its interest-rate strategies. A relatively long average duration and an emphasis on municipal bonds with longer maturities proved supportive during market rallies, but the same positioning made the fund more sensitive to rising interest rates over the reporting period’s second half.

Our sector allocation and security selection strategies produced better results in general and relative to the Index. An emphasis on higher-yielding revenue-backed bonds was also additive to performance. The fund achieved particularly favorable contributions from revenue bonds backed by airports, water and sewer facilities, and states’ settlement of litigation with U.S. tobacco companies. The fund further benefited from lack of exposure to distressed Puerto Rico securities. These positions offset relatively weak results from municipal bonds backed by revenues from health care facilities, public power plants, and special taxes.

Positioned for a Constructive Market Environment

The municipal bond market recently has shown signs of renewed strength. Investors who may have overreacted to the tax implications of the presidential election appear to have adopted a more balanced perspective. In addition, municipal bonds historically have proved less sensitive to rising interest rates than U.S. Treasury securities with comparable maturities, and municipal bonds ended the reporting period with attractive after-tax yields compared to U.S. Treasuries with comparable maturities.

As of the end of the reporting period, we have maintained the fund’s emphasis on higher-yielding revenue-backed bonds. We also have retained relatively light exposure to general obligation bonds, particularly from issuers struggling with pension funding shortfalls. We have continued to set the fund’s average duration in a modestly long position to try to take advantage of the incremental yield offered by intermediate-term and longer-maturity bonds.

May 15, 2017

Bonds are subject generally to interest-rate, credit, liquidity, and market risks, to varying degrees, all of which are more fully described in the fund’s prospectus. Generally, all other factors being equal, bond prices are inversely related to interest-rate changes, and rate increases can cause price declines.

The amount of public information available about municipal bonds is generally less than that for corporate equities or bonds. Special factors, such as legislative changes, and state and local economic and business developments, may adversely affect the yield and/or value of the fund’s investments in municipal bonds. Other factors include the general conditions of the municipal bond market, the size of the particular offering, the maturity of the obligation, and the rating of the issue. Changes in economic, business, or political conditions relating to a particular municipal project, municipality, or state in which the fund invests may have an impact on the fund’s share price.

¹Total return includes reinvestment of dividends and any capital gains paid, and does not take into consideration the maximum initial sales charge in the case of Class A shares or the applicable contingent deferred sales charge imposed on redemptions in the case of Class C shares. Had these charges been reflected, returns would have been lower. Class I, Class Y and Class Z are not subject to any initial or deferred sales charge. Past performance is no guarantee of future results. Share price, yield, and investment return fluctuate such that upon redemption, fund shares may be worth more or less than their original cost. Income may be subject to state and local taxes, and some income may be subject to the federal alternative minimum tax (AMT) for certain investors. Capital gains, if any, are taxable.

FUND PERFORMANCE

Comparison of change in value of $10,000 investment in Dreyfus Municipal Bond Opportunity Fund Class A shares, Class C shares, Class I shares, Class Y shares and Class Z shares and the Bloomberg Barclays U.S. Municipal Bond Index (the “Index”).

^†Source: Lipper Inc.

^††The total return figures presented for Class I and Class Y shares of the fund reflect the performance of the fund’s Class A shares for the period prior to 8/31/16 (the inception date for Class I and Y shares), not reflecting the applicable sales load for Class A shares.

Past performance is not predictive of future performance.

The above graph compares a $10,000 investment made in each of the Class A, Class C, Class I, Class Y and Class Z shares of Dreyfus Municipal Bond Opportunity Fund on 4/30/07 to a $10,000 investment made in the Index on that date. All dividends and capital gain distributions are reinvested.

The fund invests primarily in municipal securities and its performance shown in the line graph above takes into account the maximum initial sales charge on Class A shares and all other applicable fees and expenses on all classes. The Index, unlike the fund, covers the USD-denominated long-term tax-exempt bond market. These factors can contribute to the Index potentially outperforming or underperforming the fund. Unlike a mutual fund, the Index is not subject to charges, fees and other expenses. Investors cannot invest directly in any index. Further information relating to fund performance, including expense reimbursements, if applicable, is contained in the Financial Highlights section of the prospectus and elsewhere in this report.

COMPARING YOUR FUND’S EXPENSES
WITH THOSE OF OTHER FUNDS (Unaudited)

Using the SEC’s method to compare expenses

The Securities and Exchange Commission (SEC) has established guidelines to help investors assess fund expenses. Per these guidelines, the table below shows your fund’s expenses based on a $1,000 investment, assuming a hypothetical 5% annualized return. You can use this information to compare the ongoing expenses (but not transaction expenses or total cost) of investing in the fund with those of other funds. All mutual fund shareholder reports will provide this information to help you make this comparison. Please note that you cannot use this information to estimate your actual ending account balance and expenses paid during the period.

Expenses and Value of a $1,000 Investment
assuming a hypothetical 5% annualized return for the six months ended April 30, 2017
	Class A	Class C	Class I	Class Y	Class Z
Expenses paid per $1,000†	$4.81	$8.60	$3.71	$4.36	$4.51
Ending value (after expenses)	$1,020.03	$1,016.27	$1,021.12	$1,020.48	$1,020.33

†Expenses are equal to the fund’s annualized expense ratio of .96% for Class A, 1.72% for Class C, .74% for Class I, .87% for Class Y and .90% for Class Z, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period).

NOTES TO FINANCIAL STATEMENTS

NOTE 1—Significant Accounting Policies:

Dreyfus Municipal Bond Opportunity Fund (the “fund”) is registered under the Investment Company Act of 1940, as amended (the “Act”), as a diversified open-ended management investment company. The fund’s investment objective is to seek to maximize current income exempt from federal income tax to the extent consistent with the preservation of capital. The Dreyfus Corporation (the “Manager” or “Dreyfus”), a wholly-owned subsidiary of The Bank of New York Mellon Corporation (“BNY Mellon”), serves as the fund’s investment adviser.

On August 31, 2016,the fund commenced offering Class I and Class Y shares.

Effective March 31, 2017, the fund authorized the issuance of Class T shares, but, as of the date of this report, the fund did not offer Class T shares for purchase.

MBSC Securities Corporation (the “Distributor”), a wholly-owned subsidiary of Dreyfus, is the distributor of the fund’s shares. The fund is authorized to issue an unlimited number of $.001 par value shares of Beneficial Interest in each of the following classes of shares: Class A, Class C, Class I, Class T, Class Y and Class Z. Class A and Class T shares generally are subject to a sales charge imposed at the time of purchase. Class C shares are subject to a contingent deferred sales charge (“CDSC”) imposed on Class C shares redeemed within one year of purchase. Class I and Class Y shares are sold at net asset value per share generally to institutional investors. Class Z shares are sold at net asset value per share to certain shareholders of the fund. Class Z shares generally are not available for new accounts. Other differences between the classes include the services offered to and the expenses borne by each class, the allocation of certain transfer agency costs, and certain voting rights. Income, expenses (other than expenses attributable to a specific class), and realized and unrealized gains or losses on investments are allocated to each class of shares based on its relative net assets.

The Financial Accounting Standards Board (“FASB”) Accounting Standards Codification is the exclusive reference of authoritative U.S. generally accepted accounting principles (“GAAP”) recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the Securities and Exchange Commission (“SEC”) under authority of federal laws are also sources of authoritative GAAP for SEC registrants. The fund’s financial statements are prepared in accordance with

28

GAAP, which may require the use of management estimates and assumptions. Actual results could differ from those estimates.

The fundenters into contracts that contain a variety of indemnifications. The fund’s maximum exposure under these arrangements is unknown. The fund does not anticipate recognizing any loss related to these arrangements.

(a) Portfolio valuation: The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e., the exit price). GAAP establishes a fair value hierarchy that prioritizes the inputs of valuation techniques used to measure fair value. This hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).

Additionally, GAAP provides guidance on determining whether the volume and activity in a market has decreased significantly and whether such a decrease in activity results in transactions that are not orderly. GAAP requires enhanced disclosures around valuation inputs and techniques used during annual and interim periods.

Various inputs are used in determining the value of the fund’s investments relating to fair value measurements. These inputs are summarized in the three broad levels listed below:

Level 1—unadjusted quoted prices in active markets for identical investments.

Level 2—other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.).

Level 3—significant unobservable inputs (including the fund’s own assumptions in determining the fair value of investments).

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

Changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy. Valuation techniques used to value the fund’s investments are as follows:

Investments in securities are valued each business day by an independent pricing service (the “Service”) approved by the the fund’s Board of Trustees (the “Board”). Investments for which quoted bid prices are readily available and are representative of the bid side of the market in the

29

NOTES TO FINANCIAL STATEMENTS (continued)

judgment of the Service are valued at the mean between the quoted bid prices (as obtained by the Service from dealers in such securities) and asked prices (as calculated by the Service based upon its evaluation of the market for such securities). Other investments (which constitute a majority of the portfolio securities) are carried at fair value as determined by the Service, based on methods which include consideration of the following: yields or prices of municipal securities of comparable quality, coupon, maturity and type; indications as to values from dealers; and general market conditions. All of the preceding securities are generally categorized within Level 2 of the fair value hierarchy.

The Service is engaged under the general supervision of the Board.

When market quotations or official closing prices are not readily available, or are determined not to reflect accurately fair value, such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded, but before the fund calculates its net asset value, the fund may value these investments at fair value as determined in accordance with the procedures approved by the Board. Certain factors may be considered when fair valuing investments such as: fundamental analytical data, the nature and duration of restrictions on disposition, an evaluation of the forces that influence the market in which the securities are purchased and sold, and public trading in similar securities of the issuer or comparable issuers. These securities are either categorized within Level 2 or 3 of the fair value hierarchy depending on the relevant inputs used.

For restricted securities where observable inputs are limited, assumptions about market activity and risk are used and are generally categorized within Level 3 of the fair value hierarchy.

The following is a summary of the inputs used as of April 30, 2017in valuing the fund’s investments:

	Level 1 - Unadjusted Quoted Prices	Level 2 - Other Significant Observable Inputs	Level 3 - Significant Unobservable Inputs	Total
Assets ($)
Investments in Securities:
Municipal Bonds†	—	374,045,706	96,750	374,142,456

^†See Statement of Investments for additional detailed categorizations.

At April 30, 2017, there were no transfers between levels of the fair value hierarchy.

30

The following is a reconciliation of Level 3 assets for which significant unobservable inputs were used to determine the fair value:

	Municipal Bonds ($)
Balance as of 4/30/2016	64,498
Realized gain (loss)	—
Change in unrealized appreciation (depreciation)	32,252

The amount of total gains (losses) for the period included in earnings attributable to the change in unrealized gains (losses) relating to investments still held at 4/30/2017	32,252

(b) Securities transactions and investment income: Securities transactions are recorded on a trade date basis. Realized gains and losses from securities transactions are recorded on the identified cost basis. Interest income, adjusted for accretion of discount and amortization of premium on investments, is earned from settlement date and recognized on the accrual basis. Securities purchased or sold on a when issued or delayed delivery basis may be settled a month or more after the trade date.

(c) Dividends and distributions to shareholders: It is the policy of the fund to declare dividends daily from investment income-net. Such dividends are paid monthly. Dividends from net realized capital gains, if any, are normally declared and paid annually, but the fund may make distributions on a more frequent basis to comply with the distribution requirements of the Internal Revenue Code of 1986, as amended (the “Code”). To the extent that net realized capital gains can be offset by capital loss carryovers, it is the policy of the fund not to distribute such gains. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

(d) Federal income taxes: It is the policy of the fund to continue to qualify as a regulated investment company, which can distribute tax-exempt dividends, by complying with the applicable provisions of the Code, and to make distributions of income and net realized capital gain sufficient to relieve it from substantially all federal income and excise taxes.

As of and during the period ended April 30, 2017, the fund did not have any liabilities for any uncertain tax positions. The fund recognizes interest and penalties, if any, related to uncertain tax positions as income tax expense in the Statement of Operations. During the period ended April 30, 2017, the fund did not incur any interest or penalties.

31

NOTES TO FINANCIAL STATEMENTS (continued)

Each tax year in the four-year period ended April 30, 2017 remains subject to examination by the Internal Revenue Service and state taxing authorities.

At April 30, 2017, the components of accumulated earnings on a tax basis were as follows: undistributed tax-exempt income $665,758, accumulated capital losses $20,000,362 and unrealized appreciation $18,854,578.

Under the Regulated Investment Company Modernization Act of 2010 (the “2010 Act”), the fund is permitted to carry forward capital losses incurred in taxable years beginning after December 22, 2010 (“post-enactment losses”) for an unlimited period. Furthermore, post-enactment capital loss carryovers retain their character as either short-term or long-term capital losses rather than short-term as they were under previous statute. The 2010 Act requires post-enactment losses to be utilized before the utilization of losses incurred in taxable years prior to the effective date of the 2010 Act (“pre-enactment losses”). As a result of this ordering rule, pre-enactment losses may be more likely to expire unused.

The accumulated capital loss carryover is available for federal income tax purposes to be applied against future netrealized capital gains, if any, realized subsequent to April 30, 2017. If not applied, $16,105,988 of the carryover expires in fiscal year 2018 and $3,894,374 expires in fiscal year 2019.

The tax character of distributions paid to shareholders during the fiscal periods ended April 30, 2017 and April 30, 2016 were as follows: tax-exempt income $11,851,542 and $13,122,602, and ordinary income $32,413 and $25,771, respectively.

During the period ended April 30, 2017, as a result of permanent book to tax differences, primarily due to the tax treatment for amortization adjustments and dividend reclassification, the fund decreased accumulated undistributed investment income-net by $7,896, decreased accumulated net realized gain (loss) on investments by $32,950 and increased paid-in capital by $40,846. Net assets and net asset value per share were not affected by this reclassification.

NOTE 2—Bank Lines of Credit:

The fund participates with other Dreyfus-managed funds in an $810 million unsecured credit facility led by Citibank, N.A. and a $300 million unsecured credit facility provided by The Bank of New York Mellon, a subsidiary of BNY Mellon and an affiliate of Dreyfus (each, a “Facility”), each to be utilized primarily for temporary or emergency purposes, including the financing of redemptions. Prior to October 5, 2016, the

32

unsecured credit facility with Citibank, N.A. was $555 million. In connection therewith, the fund has agreed to pay its pro rata portion of commitment fees for each Facility. Interest is charged to the fund based on rates determined pursuant to the terms of the respective Facility at the time of borrowing. During the period ended April 30, 2017, the fund did not borrow under the Facilities.

NOTE 3—Management Fee and Other Transactions with Affiliates:

(a) Pursuant to a management agreement with Dreyfus, the management fee is computed at the annual rate of .55% of the value of the fund’s average daily net assets and is payable monthly.

During the period ended April 30, 2017, the Distributor retained $3,756 from commissions earned on sales of the fund’s Class A shares and $7,589 from CDSCs on redemptions of the fund’s Class C shares.

(b) Under the Distribution Plan adopted pursuant to Rule 12b-1 under the Act, Class C shares pay the Distributor for distributing its shares at an annual rate of .75% of the value of its average daily net assets. During the period ended April 30, 2017, Class C shares were charged $78,279 pursuant to the Distribution Plan.

(c) Under the Shareholder Services Plan, Class A and Class C shares pay the Distributor at an annual rate of .25% of the value of their average daily net assets and Class Z shares reimburse the Distributor at an annual rate of .20% of the value of its average daily net assets for the provision of certain services. The services provided may include personal services relating to shareholder accounts, such as answering shareholder inquiries regarding the fund and providing reports and other information, and services related to the maintenance of shareholder accounts. The Distributor may make payments to Service Agents (securities dealers, financial institutions or other industry professionals) with respect to these services. The Distributor determines the amounts to be paid to Service Agents. During the period ended April 30, 2017, Class A, Class C and Class Z shares were charged $444,274, $26,093 and $415,548, respectively, pursuant to the Shareholder Services Plan.

The fund has arrangements with the transfer agent and the custodian whereby the fund may receive earnings credits when positive cash balances are maintained, which are used to offset transfer agency and custody fees. For financial reporting purposes, the fund includes net earnings credits as an expense offset in the Statement of Operations.

33

NOTES TO FINANCIAL STATEMENTS (continued)

The fund compensates Dreyfus Transfer, Inc., a wholly-owned subsidiary of Dreyfus, under a transfer agency agreement for providing transfer agency and cash management services for the fund. The majority of transfer agency fees are comprised of amounts paid on a per account basis, while cash management fees are related to fund subscriptions and redemptions. During the period ended April 30, 2017, the fund was charged $116,421 for transfer agency services and $6,870 for cash management services. These fees are included in Shareholder servicing costs in the Statement of Operations. Cash management fees were partially offset by earnings credits of $4,525.

The fund compensates The Bank of New York Mellon under a custody agreement for providing custodial services for the fund. These fees are determined based on net assets, geographic region and transaction activity. During the period ended April 30, 2017, the fund was charged $24,400 pursuant to the custody agreement.

The fund compensates The Bank of New York Mellon under a shareholder redemption draft processing agreement for providing certain services related to the fund’s check writing privilege. During the period ended April 30, 2017, the fund was charged $4,605 pursuant to the agreement, which is included in Shareholder servicing costs in the Statement of Operations.

During the period ended April 30, 2017, the fund was charged $11,394 for services performed by the Chief Compliance Officer and his staff.

The components of “Due to the Dreyfus Corporation and affiliates” in the Statement of Assets and Liabilities consist of: management fees $172,391, Distribution Plan fees $6,062, Shareholder Services Plan fees $69,052, custodian fees $10,030, Chief Compliance Officer fees $3,861 and transfer agency fees $22,349.

(d) Each Board member also serves as a Board member of other funds within the Dreyfus complex. Annual retainer fees and attendance fees are allocated to each fund based on net assets.

NOTE 4—Securities Transactions:

The aggregate amount of purchases and sales of investment securities, excluding short-term securities, during the period ended April 30, 2017, amounted to $82,123,624 and $93,780,848, respectively.

At April 30, 2017, the cost of investments for federal income tax purposes was $355,287,878; accordingly, accumulated net unrealized appreciation on investments was $18,854,578, consisting of $22,342,888 gross unrealized appreciation and $3,488,310 gross unrealized depreciation.

REPORT OF INDEPENDENT REGISTERED
PUBLIC ACCOUNTING FIRM

Shareholders and Board of Trustees
Dreyfus Municipal Bond Opportunity Fund

We have audited the accompanying statement of assets and liabilities of Dreyfus Municipal Bond Opportunity Fund, including the statement of investments, as of April 30, 2017, and the related statement of operations for the year then ended, the statement of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the periods indicated therein. These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Fund’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of April 30, 2017 by correspondence with the custodian and others. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Dreyfus Municipal Bond Opportunity Fund at April 30, 2017, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the indicated periods, in conformity with U.S. generally accepted accounting principles.

Item 4.             Principal Accountant Fees and Services.

(a)  Audit Fees.  The aggregate fees billed for each of the last two fiscal years (the "Reporting Periods") for professional services rendered by the Registrant's principal accountant (the "Auditor") for the audit of the Registrant's annual financial statements or services that are normally provided by the Auditor in connection with the statutory and regulatory filings or engagements for the Reporting Periods, were $34,452 in 2016 and $35,313 in 2017.

The aggregate fees billed in the Reporting Periods for non-audit assurance and related services by the Auditor to the Registrant's investment adviser (not including any sub-investment adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by or under common control with the investment adviser that provides ongoing services to the Registrant ("Service Affiliates"), that were reasonably related to the performance of the annual audit of the Service Affiliate, which required pre-approval by the Audit Committee were $0 in 2016 and $0 in 2017.

The pre-approved services in the Policy can include pre-approved audit services, pre-approved audit-related services, pre-approved tax services and pre-approved all other services. Pre-approval considerations include whether the proposed services are compatible with maintaining the Auditor's independence. Pre-approvals pursuant to the Policy are considered annually.

EX-99.CODE ETH

THE DREYFUS FAMILY OF FUNDS

CODE OF ETHICS FOR PRINCIPAL EXECUTIVE

AND SENIOR FINANCIAL OFFICERS

1.Covered Officers/Purpose of the Code

This code of ethics (the "Code") for the investment companies within the complex (each, a "Fund") applies to each Fund's Principal Executive Officer, Principal Financial Officer, Principal Accounting Officer or Controller, or other persons performing similar functions, each of whom is listed on Exhibit A(the "Covered Officers"), for the purpose of promoting:

·honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;

·full, fair, accurate, timely and understandable disclosure in reports and documents that the Fund files with, or submits to, the Securities and Exchange Commission (the "SEC") and in other public communications made by the Fund;

·compliance with applicable laws and governmental rules and regulations;

·the prompt internal reporting of violations of the Code to an appropriate person or persons identified in the Code; and

·accountability for adherence to the Code.

Each Covered Officer should adhere to a high standard of business ethics and should be sensitive to situations that may give rise to actual as well as apparent conflicts of interest.

2.Covered Officers Should Handle Ethically Actual and Apparent Conflicts of Interest

Overview. A "conflict of interest" occurs when a Covered Officer's private interest interferes with the interests of, or his service to, the Fund.  For example, a conflict of interest would arise if a Covered Officer, or a member of his family, receives improper personal benefits as a result of his position with the Fund.

Certain conflicts of interest arise out of the relationships between Covered Officers and the Fund and already are subject to conflict of interest provisions in the Investment Company Act of 1940, as amended (the "Investment Company Act"), and the Investment Advisers Act of 1940, as amended (the "Investment Advisers Act"). For example, Covered Officers may not individually engage in certain transactions (such as the purchase or sale of securities or other property) with the Fund because of their status as "affiliated persons" of the Fund. The compliance programs and procedures of the Fund and the Fund's investment adviser (the "Adviser") are designed to prevent, or identify and correct, violations of these provisions. The Code does not, and is not intended to, repeat or replace these programs and procedures, and the circumstances they cover fall outside of the parameters of the Code.

Although typically not presenting an opportunity for improper personal benefit, conflicts arise from, or as a result of, the contractual relationship between the Fund and the Adviser of which the Covered Officers are also officers or employees.  As a result, the Code recognizes that the Covered Officers, in the ordinary course of their duties (whether formally for the Fund or for the Adviser, or for both), will be involved in establishing policies and implementing decisions that will have different effects on the Adviser and the Fund. The participation of the Covered Officers in such activities is inherent in the contractual relationship between the Fund and the Adviser and is consistent with the performance by the Covered Officers of their duties as officers of the Fund and, if addressed in conformity with the provisions of the Investment Company Act and the Investment Advisers Act, will be deemed to have been handled ethically. In addition, it is recognized by the Fund's Board that the Covered Officers also may be officers or employees of one or more other investment companies covered by this or other codes of ethics.

Other conflicts of interest are covered by the Code, even if such conflicts of interest are not subject to provisions in the Investment Company Act and the Investment Advisers Act.  Covered Officers should keep in mind that the Code cannot enumerate every possible scenario.  The overarching principle of the Code is that the personal interest of a Covered Officer should not be placed improperly before the interest of the Fund.

Each Covered Officer must:

·not use his personal influence or personal relationships improperly to influence investment decisions or financial reporting by the Fund whereby the Covered Officer would benefit personally to the detriment of the Fund;

·not cause the Fund to take action, or fail to take action, for the individual personal benefit of the Covered Officer rather than the benefit of the Fund; and

·not retaliate against any employee or Covered Officer for reports of potential violations that are made in good faith.

3.Disclosure and Compliance

·Each Covered Officer should familiarize himself with the disclosure requirements generally applicable to the Fund within his area of responsibility;

·each Covered Officer should not knowingly misrepresent, or cause others to misrepresent, facts about the Fund to others, whether within or outside the Fund, including to the Fund's Board members and auditors, and to governmental regulators and self-regulatory organizations;

·each Covered Officer should, to the extent appropriate within his area of responsibility, consult with other officers and employees of the Fund and the Adviser with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents the Fund files with, or submits to, the SEC and in other public communications made by the Fund; and

·it is the responsibility of each Covered Officer to promote compliance with the standards and restrictions imposed by applicable laws, rules and regulations.

4.Reporting and Accountability

Each Covered Officer must:

·upon adoption of the Code (or thereafter, as applicable, upon becoming a Covered Officer), affirm in writing to the Board that he has received, read, and understands the Code;

·annually thereafter affirm to the Board that he has complied with the requirements of the Code; and

·notify the Adviser's General Counsel (the "General Counsel") promptly if he knows of any violation of the Code.  Failure to do so is itself a violation of the Code.

The General Counsel is responsible for applying the Code to specific situations in which questions are presented under it and has the authority to interpret the Code in any particular situation. However, waivers sought by any Covered Officer will be considered by the Fund's Board.

The Fund will follow these procedures in investigating and enforcing the Code:

·the General Counsel will take all appropriate action to investigate any potential violations reported to him;

·if, after such investigation, the General Counsel believes that no violation has occurred, the General Counsel is not required to take any further action;

·any matter that the General Counsel believes is a violation will be reported to the Board;

·if the Board concurs that a violation has occurred, it will consider appropriate action, which may include: review of, and appropriate modifications to, applicable policies and procedures; notification to appropriate personnel of the Adviser or its board; or dismissal of the Covered Officer;

·the Board will be responsible for granting waivers, as appropriate; and

·any waivers of or amendments to the Code, to the extent required, will be disclosed as provided by SEC rules.

5.Other Policies and Procedures

The Code shall be the sole code of ethics adopted by the Fund for purposes of Section 406 of the Sarbanes-Oxley Act of 2002 and the rules and forms applicable to registered investment companies thereunder. The Fund's, its principal underwriter's and the Adviser's codes of ethics under Rule 17j-1 under the Investment Company Act and the Adviser's additional policies and procedures, including its Code of Conduct, are separate requirements applying to the Covered Officers and others, and are not part of the Code.

6.Amendments 

The Code may not be amended except in written form, which is specifically approved or ratified by a majority vote of the Fund's Board, including a majority of independent Board members.

7.Confidentiality 

All reports and records prepared or maintained pursuant to the Code will be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or the Code, such matters shall not be disclosed to anyone other than the appropriate Funds and their counsel, the appropriate Boards (or Committees) and their counsel and the Adviser. 

8.Internal Use

The Code is intended solely for the internal use by the Fund and does not constitute an admission, by or on behalf of the Fund, as to any fact, circumstance, or legal conclusion.
