In NCIC, a gun can be entered as which of the following?

In the National Crime Information Center (NCIC) database, firearms can be categorized in specific ways to effectively track their status and ensure law enforcement agencies have accurate information regarding these items. The correct classification for a gun includes being labeled as "Stolen," indicating it was unlawfully taken, "Lost," referring to a firearm misplaced or reported as missing by its owner, "Recovered," which means it has been found or taken back by authorities, and "Felony," which refers to guns associated with a felony crime.

This classification is crucial as it allows law enforcement to understand the circumstances surrounding the firearm's status and to coordinate efforts regarding potential investigations or legal proceedings. The other options listed do not fully encompass the recognized categories in NCIC for tracking firearms, making them less appropriate for this context.
