What part holds the pressure caused by the propellant being ignited?

Chamber Barrel Muzzle Fuze

Correct Answer:

Chamber

Explanation:

When the propellant is ignited, it generates a surge of gas that must be contained so the bullet can be propelled forward. The space that holds this high-pressure gas is the chamber—the sealed area where the cartridge sits. The chamber’s walls withstand the peak pressure long enough for the bullet to begin moving into the barrel. The barrel is simply the path the bullet travels through; it experiences pressure as the gas pushes the bullet, but the container that holds the gas is the chamber (with the cartridge case). A fuze relates to ignition timing in explosive shells, not to containing chamber pressure in a firearm.
