What does Cisco use for Return Materials Authorization tracking of field-replaceable parts?

Cisco uses a Return Materials Authorization (RMA) number as the unique identifier to track the entire process of returning a defective field-replaceable part and receiving a replacement. When a service request is initiated with the Cisco Technical Assistance Center (TAC) and a hardware replacement is deemed necessary, an RMA order is created. This order is assigned a unique RMA number, which serves as the primary reference for tracking the shipment of the replacement part, the return of the defective unit, and all associated logistics until the case is closed.

A. product number: A product number (or part number) identifies a specific model or type of hardware, not a unique physical unit or a specific return transaction.
B. serial number: A serial number uniquely identifies the specific piece of hardware being replaced, but it does not track the logistics and authorization of the return process itself; the RMA number does.
D. FRU number: A Field Replaceable Unit (FRU) number is a type of part number for a component. It identifies the kind of part, not the specific service transaction for its replacement. ---
