Dynamic friction it means body or parts is in motion with other parts and in rolling friction parts is circulated with respect to other.

It is B.
When a body is moving over a surface, the friction acting on it is kinetic friction.
When a body is at rest, the friction acting is static friction.
When a body is moving over a surface, the friction acting on it is kinetic friction.
When a body is at rest, the friction acting is static friction.

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.
