Answer:
The correct answer is option B.
Step-by-step explanation:
The light-dependent reactions in the process of photosynthesis utilize Sun's light energy to dissociate water, known as photolysis. Water after getting dissociated produces hydrogen, oxygen, and electrons. The electrons move through the compositions in the chloroplasts and by the process of chemiosmosis, produce ATP.
The hydrogen gets transformed into NADPH, which is further utilized in the light-independent reactions. While oxygen diffuses out of the plant as a waste component of photosynthesis into the atmosphere. All this takes place in the grana thylakoids of the chloroplasts.
