Answer: The correct answer is -
Option C).
Step-by-step explanation:
Dark reaction (also termed as calvin cycle) is the second stage of the photosynthesis (process of formation of food in green plants and algae) that occurs in the stroma of chloroplast.
This stage is dependent on the products of light reaction (first stage of photosynthesis) that are NADPH and ATP.
Using these products, CO2 (carbon dioxide) is fixed and converted into food (glucose, which is a carbohydrate or sugar).
Thus, option C) is the right answer.
