The questions in not ask particular friction so dynamic friction Will be right because the questions in the not given the surface type so friction depends on the surface.

Thanks @Sriram.

When the body is in rest, it has a resistant to move because of static friction. Whenever it overcomes that friction it goes under dynamic friction.

When the body gets rolling friction ?

@Niel, you are absolutely correct. But the most appropriate answer is Dynamic friction. All the rolling friction is a dynamic friction but the reverse is not true. A relative motion of a block on a slope is a dynamic friction and not a rolling friction. A ball bearing or wheels moving on a road experience rolling friction which may be termed as dynamic friction even.

You are right friends, but if bodies have wheel like surface then there is rolling friction, and it is not specified here. So? I think it can be A also.

When the body is moving to contact with surface then some force oppose the motion of body called friction. But the body in motion so it is called dynamic friction.

When two body subjected to relative motion is called dynamic friction.

Since the body is in motion, opposite force is generated to restrict the motion of the body as kinetic friction or dynamic friction.
