If an object is moving at a constant speed, it means that there is no acceleration, which means there can be no net forces acting on the object. Therefore, D is the correct choice as it states that no net force is acting on the object. A, B, C, and E can be ruled out as they all imply the presence of a net force, which is not possible if the object is moving at a constant speed.
