Sales Ledger Control Account's Error Detection Role

Steps:

• Recall that a sales ledger control account summarizes totals from individual customer accounts in the sales ledger.
• Understand its integration in the double-entry system, posting totals like sales, receipts, and discounts to the control account.
• Compare the control account balance with the total of individual sales ledger accounts periodically.
• Identify discrepancies between these totals to pinpoint errors in posting or calculations.

Why A is correct:

• D: Contras involve offsetting entries between sales and purchases ledgers for mutual dealings, unrelated to the control account's primary function.

Final answer: A
