Answer:
Object C has the most potential energy. This is based off the assumption that all three objects are uniform and crafted of the same material.
Step-by-step explanation:
In the given diagram, the question pertains to identifying the object with the greatest potential energy among three objects: A, B, and C, positioned at different heights above the ground.
Potential energy is a concept in physics that describes the energy an object possesses due to its position. In this case, potential energy is related to the height of the objects above the ground. The formula for gravitational potential energy is given by:

Based on the diagram's description, object C is larger than object B and both are positioned at the same level above the ground. This suggests that object C likely has a higher mass than object B. Since the potential energy is proportional to both the mass and height, and since the height is the same for both objects, object C would indeed have a greater potential energy compared to object B due to its greater mass.
Object A, on the other hand, is positioned closer to the ground. Since it has the least height among the three objects, its potential energy will be the lowest.
Therefore, among the objects in the diagram, object C, being larger and at the same height as object B, would possess the most potential energy.
