Errors Causing Trial Balance Imbalance

Steps:

• Trial balance requires total debits to equal total credits; errors disrupting this parity cause imbalance.
• Examine each option for impact on debit-credit equality.
• Option A: Rent payment should debit rent $250 and credit bank$250; debiting bank instead creates two debits ($500 total) with no credit, unbalancing by$500.
• Options B, C, D: Each affects debits and credits equally or not at all, preserving balance.

Why A is correct:

• It violates the double-entry rule (every transaction must have equal debits and credits), resulting in excess debits.

Why the others are wrong:

• B: Undercasts purchases and corresponding credit equally by $45, maintaining balance.
• C: Omission skips equal debit (receivable) and credit (sales) of $160, so no net imbalance.
• D: Incorrect accounts but equal debit ($500 to customer) and credit ($500 to purchases return), balancing overall.

Final answer: A
