Answer: D. a paint can being carried up a ladder
Explanation: Potential energy is the energy possessed by an object by virtue of its height.
\(P.E=m\times g\times h\)
m= mass
g = acceleration due to gravity
h = height
Thus Potential energy is directly proportional to the height of the body. The greater the height, greater is the potential energy. Thus a paint can being carried up a ladder will lead to increase in potential energy as height will keep on increasing.
