Which small pistol has a large bore and is effective at close range?

• A. Derringers
• B. Hemoglobin
• C. Hemorrhage
• D. Heroin

Answer: (A)

This question tests understanding of firearm design suited for close-range use. Derringers are compact pocket pistols that carry a relatively large caliber for their tiny frame. That combination gives more stopping power in a small, easily concealable weapon, which is why they’re described as a large-bore pistol effective at close range. Their design emphasizes quick draw and simple operation over long-range accuracy, making them useful when engagement happens at very short distances.

The other options aren’t firearms at all—hemoglobin is a blood protein, hemorrhage is excessive bleeding, and heroin is a drug—so they don’t fit the description of a small pistol with a large bore used at close range.
