Final answer:
The correct option is B. Sending the request was meaningless because the account was closed before the year-end.
The major flaw in this audit procedure is that sending the bank confirmation request for a closed account was meaningless because it provides no relevant information on the year-end status of that account.
Step-by-step explanation:
The major flaw in the audit procedure described is B. Sending the request was meaningless because the account was closed before the year-end. When performing an audit, it is crucial to confirm the existence and status of bank accounts as of the year-end date.
If an account has been closed, a confirmation request does not provide relevant information regarding the current status or balance. Moreover, sending a confirmation for a closed account could potentially waste time and resources, and may not meet the audit objectives. Rather, the auditor should have verified the closure of the account and focused on examining the entity's final transactions and reconciling items up to the closure date.
