What is the line of fire in firearms safety?

• A. The height of the shooter from the ground.
• B. The angle at which the bullet leaves the barrel.
• C. The sequence of events during a shot.
• D. The path from muzzle to target.

Answer: (D)

Line of fire means the path a projectile travels from the muzzle to the target, including anything in between. This is the safety boundary you must check before firing: ensure that area is clear of people, animals, and unintended objects because anything in that path can be hit. That’s why the correct answer describes the path from the muzzle to the target. The other ideas aren’t about the safety boundary: the shooter’s height doesn’t define the projectile’s path; the angle at which the bullet leaves the barrel concerns trajectory rather than the safety line; and the sequence of events during a shot relates to procedure rather than where the bullet could go.
