Solution

The correct option is D Laptop
Solar energy is the energy recieved from the sun. Some electrical devices such as calculators and solar heaters have solar cells which convert solar energy to electricity and help them to function.
A solar cooker cooks food using the heat energy from the sun. Hence it is also a device that works using solar energy.
However, a laptop does not need solar energy to function.
