E) Its acceleration is in the same direction as it velocity.

When an object moves with constant non-zero velocity, it means there is no acceleration. According to Newton's first law of motion, an object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Therefore, the net force on the object must be zero for it to maintain constant velocity.
