Answer:
Correct option shown in figure
Explanation:
Gravitational Potential Energy
It's the capacity of doing work of an object depending on its height above the ground level or any chosen reference. Its formula is
U=m.g.h
where m is the mass of the object, g is the acceleration of gravity and h is the height
Note the potential energy depends linearly on the height of the object, thus the function U vs h is a straight increasing line
The correct graph is shown in the figure attached (third graph)
