When you need to verify a specific transaction's lifecycle, you would consult what?

• A. Balance sheet.
• B. Audit trail.
• C. Income statement.
• D. Reconciliation report.

Answer: (B)

Tracking the full lifecycle of a single transaction hinges on an audit trail. An audit trail is a chronological record of all actions, dates, user IDs, system events, and data changes that occur from the moment the transaction is created to its final disposition. This trace lets you confirm who initiated the transaction, what approvals were given, when postings happened, and whether any reversals or reconciliations occurred. The other options don’t provide that end-to-end narrative: a balance sheet shows values at a single point in time, not the steps of one transaction; an income statement summarizes activity over a period, not the lifecycle of a specific item; a reconciliation report compares balances between records but doesn’t give a complete, step-by-step history. So, for verifying a specific transaction’s lifecycle, the audit trail is the best source.
