Question

when you know a firearms effective killing range, you can determine:
a which animals you can hunt
b which stance to use when shooting
c whether you are aiming at the target
d when a shot will give a clean kill

Explanation:

The effective killing range of a firearm helps determine when a shot will result in a clean kill. Knowing this range ensures that the shot is within the firearm's capability to humanely and effectively take down the target. Options A (which animals to hunt) is more about regulations and species - specific factors rather than just the firearm's range. Option B (stance) is about shooting technique and stability, not directly related to the range for a clean kill. Option C (aiming at the target) is about marksmanship skills like sight - alignment and sight - picture, not the range for a clean kill.

Answer:

D. when a shot will give a clean kill
