Final answer:
The bowling ball with the sharpest angle has the most potential energy.
Step-by-step explanation:
The bowling ball with the highest potential energy is Ball A, because it is placed at the sharpest angle. Potential energy is given by the formula PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object. As all the balls are identical and placed at the same height, the one with the steepest angle will have the greatest height and therefore the most potential energy.
