Solution

The correct option is A Solar energy - Chemical energy - Kinetic energy
Solar energy is converted in to electrical energy with the help of solar panels.
When the electric cell is charged, the electrical energy is converted and stored in the form of chemical energy.
This cell when connected to a toy, the chemical energy converts back to electrical energy and moves the toy resulting in kinetic energy.
