Control accounts summarize subsidiary ledgers for error detection and efficiency

Steps:

• Define control accounts as summary ledgers for receivables/payables totals from detailed subsidiary records.
• Assess each statement against control account functions: error checking, fraud reduction, and total aggregation.
• Identify mismatch: statement A limits error checks to cash book only, ignoring other sources.
• Confirm A as incorrect by verifying B, C, D align with standard accounting practices.

Why A is correct:

• Control accounts reconcile totals from all subsidiary ledger entries (sales, purchases, cash, etc.), not just cash book, per double-entry bookkeeping principles.

Why the others are wrong:

• B: Control accounts enable error detection via reconciliations between summary and detailed ledgers.
• C: They provide quick access to aggregate receivables/payables balances without scanning individual accounts.
• D: Oversight from control-subsidiary comparisons deters fraudulent ledger manipulations.

Final answer: A
