@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.

Friction due to body slides over another body, hence velocity takes place. So that it's dynamic friction.

Motion of a body is directly related to the velocity(kinematic and dynamic).

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.

Dynamics when body is in motion. When a body slides over another body friction occurs in between the two body. The friction offers resistance to the motion of the sliding body that's why motion called as dynamics motion.

When there is relative motion between two bodies, when in motion, then there exists kinetic friction between them, which is also known as dynamic friction, as external forces are also involved in this.
