Solution

The correct option is C
45 J with no change in potential energy.

Weight of the toy = 0.1 kg

Energy input = Work done to move the cart = F $\times$ displacement = 9 $\times$ 5 m = 45 J

As there is no change in the vertical height, the potential energy possessed by the toy does not change.
