Explanation:
When auditing third-party service providers, an auditor should be concerned with ownership of programs and files, a statement of due care and confidentiality, and the capability for continued service of the service provider in the event of a disaster.

This is because audit trails are records of system activity and user actions that can provide evidence of the validity and integrity of transactions and data in a financial application system. Audit trails can help to ensure compliance with laws, regulations, policies, and standards, as well as to detect and prevent fraud, errors, or misuse of information. Audit trails can also facilitate auditing, monitoring, and evaluation of the financial application system's performance and controls1.
The application should meet the organization's requirements (A) is not the best answer, because it is a general and obvious criterion that applies to any application system acquisition, not a specific and important recommendation for a financial application system. The organization's requirementsshould be clearly defined and documented in the RFP, but they may not necessarily include audit trails as a design feature.
Potential suppliers should have experience in the relevant area © is not the best answer, because it is a factor that affects the selection of the supplier, not the design of the financial application system. The experience and reputation of potential suppliers should be evaluated and verified during the RFP process, but they may not guarantee that the supplier will include audit trails in the design.
Vendor employee background checks should be conducted regularly (D) is not the best answer, because it is a measure that affects the security and trustworthiness of the vendor, not the design of the financial application system. Vendor employee background checks should be performed as part of the vendor management and due diligence process, but they may not ensure that the vendor will include audit trails in the design.
