Which of the following BEST indicates an effective internal audit quality assurance and improvement program?

The goal of a quality assurance and improvement program (QAIP) is to drive continuous enhancement in audit practices and deliver increasing value to stakeholders. Identification and implementation of opportunities for improvement demonstrate that the program is working effectively. Oversight (A) and charter updates (B) are important governance aspects, while focusing on high-risk audits (C) is a prioritization strategy. However, the hallmark of a successful QAIP is the ability to continuously identify and address gaps, streamline practices, and enhance audit value. ISACA emphasizes agility, adaptability, and ongoing improvement as key success indicators for internal audit functions.
