Solution

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

Mass of the toy = $0.1 kg$
Energy input = Work done to move the cart
$= Force \times displacement$
$= 9 \times 5 = 45 J$
As there is no change in the vertical height, the potential energy possessed by the toy does not change.
