Solution
The correct option is B NADH
The chloroplast is involved in both stages of photosynthesis. The light reaction takes place in the thylakoid discs. There, water (H20) is oxidized, and oxygen (O2) is released. The electrons freed up from the water are transferred to ATP and NADPH. The dark reaction occurs outside of the thylakoids. In this reaction, the energy from ATP and NADPH are used to fix carbon dioxide (CO2). So NADH is not a product of the light reaction of photosynthesis.
