Explanation

A functional audit evaluates whether a system or process is operating correctly and meeting its intended performance requirements - exactly what is needed to validate that the new SaaS payroll tool is configured as expected. A financial audit (A) focuses on the accuracy of financial records and statements. An administrative audit (B) examines management and organizational practices. A compliance audit (D) checks adherence to laws, regulations, or standards. Since the goal is to verify the tool performs as designed, a functional audit is most appropriate.
