The pendulum have the least potential energy at the point C between point A and B because it is lower in height as compared to other points.
Potential energy is the energy held by an object because of its position. If the object is present at a certain height, it has more potential energy as compared to object which is lower in height.
So we can conclude that the pendulum have the least potential energy at C point that is between point A and B.
