Which statement correctly contrasts hangfire and misfire?

• A. Hangfire is a complete failure to fire; Misfire is a delay in functioning
• B. Hangfire is a delay in functioning; Misfire is a delay in functioning
• C. Hangfire is immediate detonation; Misfire is delayed detonation
• D. Hangfire is a delay in functioning; Misfire is a complete failure to fire

Answer: (D)

Understanding the difference between a delayed firing and a failure to fire is what this item tests. Hangfire means there is a noticeable delay between triggering and the device detonating—the detonation eventually occurs, but after a delay. Misfire means the device does not detonate at all on the initial attempt. So, the description that matches this distinction is: hangfire is a delay in functioning and misfire is a complete failure to fire. The other statements mix up the meanings or claim both are delays or that detonation is immediate, which doesn’t fit these definitions.
