Solution

The correct option is B 0 N
As the surface is frictionless.
From newton's 1st law of motion, since there is no external force acting on the object, it will remain in its original state of motion i.e. uniform velocity.
Therefore, zero force is required to keep the object moving with constant velocity.

Hence, correct answer is B.
