An internal auditor is tasked with evaluating the adequacy of the organization's inventory fraud controls.

Comprehensive and Detailed Explanation:

Cyclic counting is a control technique used to verify inventory accuracy and prevent fraud or misstatement. While documentation of approvals (A), valuation reconciliations (D), and frequency of counts (C) all contribute to control effectiveness, the most relevant evidence for evaluating fraud control adequacy is whether the organization analyzes root causes of differences and implements corrective actions (B). Simply reconciling and adjusting balances does not address why discrepancies occur, and fraud risks remain if underlying causes go unexamined. For example, if theft or unauthorized removals are occurring, approving adjustments without corrective measures merely hides the issue. By identifying and addressing root causes, management ensures sustainable fraud prevention and strengthens internal controls. Thus, the focus must be on corrective actions tied to root cause analysis, aligning with IIA guidance on ensuring controls address risks rather than only reporting deviations.
