Comprehensive and Detailed Step-by-Step Explanation:
* Challenges with Computer-Assisted Audit Tools (CAATs):
* One of the most common issues auditors face is obtaining access to the data needed for analysis, especially when data is stored in secure or restricted systems.
* Access issues may arise due to technical restrictions, security policies, or inadequate documentation of data sources.
* Reasoning:
* Option A is correct because gaining access to relevant, complete, and reliable data is a frequent challenge when using computerized audit tools.
* Option B is less common, as CAATs are often designed for use by auditors without requiring advanced IT skills.
* Option C refers to reliance on IT personnel, which is less relevant for independent auditors using their own tools.
* Mitigating Access Challenges:
* Establishing clear communication with IT and obtaining necessary approvals in advance can help overcome data access issues.
