Wilson, CPA, completed the field work of the audit of Abco's December 31, Year 1, financial statements on March 6, Year 2, at which time Wilson believed that sufficient appropriate audit evidence had been obtained to support the auditor's opinion. However, a subsequent event requiring adjustment to the Year 1 financial statements occurred on April 10, Year 2, and came to Wilson's attention on April 24, Year 2, which preceded the issuance of the audit report on Abco's Year 1 financial statements. If the adjustment is made without disclosure of the event, Wilson's report ordinarily should be dated 

A. April 24, Year 2. 

B. April 10, Year 2. 

C. March 6, Year 2.
