This allows investigators to trace

• A. The operator's badge number
• B. To whom the cartridge was issued or sold and location of the deployment
• C. The device's serial number
• D. The time of day of deployment

Answer: (B)

Tracing who had access to a cartridge and where it was used is essential for accountability and investigations. If a cartridge can be tied to the person it was issued or sold to, and the exact deployment location, investigators can establish a clear history: who authorized or possessed the cartridge and where the incident occurred. This creates a reliable audit trail and helps verify proper use and compliance.

The other details—identifying the operator by badge alone, or the device’s serial number, or the time of deployment—do not by themselves connect the cartridge to a specific user and a specific location. They provide pieces of the puzzle, but the combination of issuance-to-a person and deployment location is what enables full traceability.
