Explanation:

Rifling refers to the spiral grooves cut inside the barrel of a firearm. When a bullet is fired, these grooves cause the bullet to spin. This spinning motion (like a gyroscope) stabilizes the bullet in flight, improving accuracy and range. Primer (A) is the part of a cartridge that ignites the gunpowder. Action (B) refers to the mechanism of a firearm that loads, fires, and ejects cartridges. Cartridge (C) is the complete round of ammunition.

Answer:

D. rifling
