Solution
Correct option is A)
Photosynthesis is the process of preparing food in the presence of sunlight and chlorophyll. In this process, the plant uses water from the soil, carbon dioxide from the air.
Carbon dioxide + Water + light energy → Glucose + Oxygen
It occurs in green plants, certain algae, blue-green algae and bacteria. During this process, carbon dioxide is reduced into glucose while water is oxidized as it is split to release electrons, protons and atomic oxygen.
