Which scenario best describes a cookoff?

• A. A hot weapon with a closed chamber
• B. A weapon that jams
• C. A round that fails to fire
• D. A weapon that misfeeds

Answer: (A)

A cookoff happens when heat in the firearm heats a chambered round enough that it will ignite on its own, without the trigger being pulled. The best fit is a hot weapon with a closed chamber because the chamber already contains a live round and the extreme heat can cause it to fire automatically. This isn’t about mechanical failures like jamming, a misfire, or a misfeed, which describe different malfunctions where ignition or feeding is disrupted or delayed rather than caused by chamber heat.
