During the process of photosynthesis, light energy is converted to chemical energy.

The correct option is A. True.

Photosynthesis:

Photosynthesis is the process by which green plants prepare their own food. The chlorophyll pigment present in green plants harness the energy of sunlight to convert carbon dioxide and water to carbohydrate (glucose) and oxygen.

Therefore solar energy is the form of light energy that is used up in the process and the carbohydrate (glucose) molecule prepared in the process is called the food of the plant. This is because the glucose is used for producing chemical energy in the plant in the form of ATP. Therefore, solar energy is converted to chemical energy during photosynthesis.
