Why cannot be potential energy to kinetic energy and dynamic to static friction please explain?

Dynamic friction:- friction offered by the body when it is moving.

Static friction:- friction offered by the body when it is in steady.

When the body is moving as compared to steady state it offers less friction than the steady state.

Therefore D is not the answer.

And in other C option when potential energy is converted into kinetic energy experience certain friction on the surface.

Both C and D both are not correct answer.

Sliding has an one direction for flow but rolling has many direction to take flow, so opposing force will be reduced.

This is because more of the body comes in contact with the surface than when rolling. Therefore while sliding friction is increased.
