Which action would confirm a product is not suspicious?

• A. The outer box shows tampering.
• B. The lot number and expiration date do not match the invoice.
• C. The invoice matches the lot number and expiration date.
• D. The product is out of date but still used.

Answer: (C)

Verifying that the records and the product match is essential for confirming legitimacy. When the invoice aligns with the product’s lot number and expiration date, it shows the item received corresponds to what was billed, supporting that it came from the expected supplier and is being tracked correctly. This alignment indicates proper traceability and reduces the likelihood of counterfeit or mislabeling. In contrast, outer-box tampering raises concerns about interference; a mismatch between the lot/expiration and the invoice suggests a potential error or counterfeit; and using an item that is expired is unsafe and not acceptable. So, matching the invoice to the lot number and expiration date is the best sign that the product is not suspicious.
