The correct option is (b) It is in dynamic equilibrium
 
The explanation is: When a body is moving with constant velocity, there is no net force or moment acting on it. Hence, the body is in equilibrium. But since the body is moving, the equilibrium is known as dynamic equilibrium. Static equilibrium occurs when the body is at rest.
