Which statement about the trial balance is true?

• A. It proves that all transactions are free of error.
• B. It lists only revenue accounts.
• C. It helps detect mathematical errors but cannot catch all posting errors or omissions.
• D. It replaces the need for a general ledger.

Answer: (C)

The trial balance is a snapshot of all ledger accounts with their ending balances, used to check that the total debits equal the total credits across the ledger. This makes it a good tool for spotting arithmetic and posting mistakes, but it does not guarantee that every transaction is free of error. Some errors won’t affect the equality of debits and credits, such as recording a wrong amount in both sides that still balances, posting a transaction to the wrong accounts in a way that nets to the same totals, or omitting a transaction entirely. Because of these limits, the trial balance cannot catch all posting errors or omissions. At the same time, a trial balance includes all accounts from the general ledger, not just revenue accounts, and it does not replace the general ledger itself. The ledger remains the complete record of all transactions, while the trial balance serves as a check on those balances.
