Answer

A - Unstable. B - Stable. C - Neutral.

Work Step by Step

Position A is an unstable equilibrium. If the ball is pushed away from this position and released, it continues moving away from equilibrium. Position B is a stable equilibrium. If the ball is pushed away from this position and released, it returns to equilibrium. Position C is a neutral equilibrium. If the ball is pushed away from this position and released, it stays at its new equilibrium position.
