Final answer:
The task that could most appropriately be delegated to the internal audit staff is selection of accounts receivable for confirmation.
Step-by-step explanation:
The task that could most appropriately be delegated to the internal audit staff in connection with the examination of financial statements by an independent auditor is a. Selection of accounts receivable for confirmation, based upon the internal auditor's judgment as to how many accounts and which accounts will provide sufficient coverage.
