Solution

Explanation of the answer:
Centripetal force is the force acting on an object in curvilinear motion directed toward the axis of rotation or centre of curvature.
The hand is towards the centre, so the centripetal force acts on it.
The direction of the centripetal force is towards the centre.
The centripetal force acts on the hand and states it is directed towards the center of the circle.
