Solution

The correct option is A Greater
The kinetic energy in bullet should be greater beacause it has less mass as compared to gun and gun experiences opposite force due to law of conservation of energy that is why we experience a backward force while shooting from a gun,which is called recoil of the gun.
So (A) is correct answer.
