* A. Determine whether the purchasing department complies with policy by examining a random selection of purchase orders:Correct. Reviewing a random sample of purchase orders is a standard procedure for evaluating compliance with purchasing policies, such as approval requirements, vendor selection, and adherence to budget constraints.
* B. Evaluate whether purchasing requests are properly approved by authorized staff by obtaining independent verification from the vendors:Vendor verification is not typically used to evaluate internal approvals as this information is available within the organization's records.
* C. Ascertain whether material receipts are recorded on a timely basis by reviewing physical inventory stock counts:Physical inventory reviews focus on inventory management and reconciliation, not specifically on the timeliness of receipts.
* D. Determine whether prices charged for goods received are correct by reviewing the appropriate accounts payable record by vendor:While reviewing accounts payable records helps verify the accuracy of pricing, it does not directly evaluate the purchasing department's adherence to procedures.
