Solution

The correct option is C greater than the acceleration of the gun
Action reaction pair is formed when bullet is fired. Equal and opposite forces act on the bullet and the gun.
Now we know that the acceleration caused due to a force= $a = \frac{F}{m}$
Thus for same force, the smaller mass object has greater acceleration. Thus the acceleration of the bullet is greater than that of gun.
