If the object has no acceleration, it means there is no net force acting on the object. In this case, if it is not at rest, it must be moving with a constant non-zero velocity. However, if it is in mechanical equilibrium, it could either be at rest or moving with a constant non-zero velocity. Therefore, the best choice is C.
