C Correct answer
Explanation

Dark reaction of photosynthesis utilises CO2. Dark reactions make use of organic energy molecules (ATP and NADPH). This reaction cycle is also called Calvin Benison Cycle, and it occurs in the stroma. ATP provides the energy, while NADPH provides the electrons required to fix the CO2 (carbon dioxide) into carbohydrates.
