Which one of the following statements with reference to weaponry is not correct ?

Automatic rifle utilises its recoil or a portion of the gas propelling the projectile to eject the spent cartridge case, load a new cartridge, and cock the weapon to fire again.

AK 47 is a weapon consisting essentially of a metal tube from which a missile is shot by the force of exploding some propellant.

An automatic rifle fires repeatedly as long as the trigger is held down until the magazine is exhausted.

AK 47 rifle can be used in automatic as well as semi-automatic mode.

Explanation

Option B is the incorrect statement. It provides a generic and simplified definition of a "gun" rather than a technically accurate description of the AK 47. In modern military terminology, a missile refers to a self-propelled or guided weapon system, whereas the AK 47 fires bullets or projectiles. Furthermore, the AK 47 is a sophisticated gas-operated assault rifle, making the description "essentially a metal tube" reductive. Option A correctly describes the self-loading mechanism (using recoil or gas-operation) that enables automatic fire. Option C accurately defines the fully automatic firing mode where the weapon continues to fire as long as the trigger is depressed. Option D is correct as the AK 47 features a fire selector switch allowing the user to toggle between semi-automatic and fully automatic modes.

With reference to Indian defence, which one of the following statements is not correct?

Statement I: When a gun is fired it recoils, i.e., it pushes back, with much less velocity than the velocity of the bullet. Statement II: Velocity of the recoiling gun is less because the gun is much heavier than the bullet.
