Answer:
The supervisor should compare the register transactions with the cash receipts report to make sure that both are correct.
Explanation:
In regards to the control of over-the-counter cash receipts, there should be one person that handles the cash and one recording the transactions in the accounting records as the duties should be separated. According to this, the answer is that the supervisor should compare the register transactions with the cash receipts report to make sure that both are correct as the cashier would handle the cash and the supervisor would register the transactions.
The other options are not right because the duties would not be separated.
