The correct answer is (C)
During photosynthesis light energy is absorbed by chlorophyll, a green substance found in chloroplasts in some plants cells and algae. Absorbed light energy(photons) is used to convert carbon dioxide(from air) and water(from soil) into sugar called as glucose. Oxygen is released as a by-product.
The energy from light is also utilized to produce ATP and NADPH. NADPH work as a electron carrier in calvin cycle, where it transform carbon dioxide into high energy sugar.
