In internal controls, an audit trail helps to detect errors and fraud by providing what?

• A. To strengthen customer loyalty programs.
• B. An auditable history of transactions.
• C. To improve packaging design.
• D. To track supplier payments.

Answer: (B)

An audit trail is an auditable history of transactions that lets you trace a transaction from its origin to its final recording in the accounts. This traceability shows who approved or changed data, when it happened, and what exactly was involved. With that information, you can spot errors or unusual activity and see exactly where something went wrong, which is how frauds are detected and prevented. In internal controls, the ability to follow a transaction step by step provides accountability and makes reconciliation and investigations much easier.

The other options don’t capture this core purpose. Strengthening customer loyalty programs, improving packaging design, or simply tracking supplier payments describe specific business activities, not the comprehensive historical traceability that an audit trail provides for all transactions.
