Answer

Brief Explanations:

According to the law of conservation of angular - momentum, an external torque is required to change the angular momentum of a system. Internal torques cancel each other out within the system and do not change the total angular momentum. Force and external force alone do not directly change angular momentum; it is the external torque (which is the cross - product of the position vector and the external force) that matters for changing angular momentum.

Answer:

D. External torque
