The correct answer is option D
Reason: All other options are incorrect as
Carbon dioxide used in the light-independent processes of photosynthesis (Celvin Cycle) are used completely to form glyceraldehyde-3-phosphate (G3P) molecule which is stable and is a six carbon molecule. Also Energy is produced in the form of NADPH and ATP.
6 CO2 enters the celvin cycle and 6 G3P molecules are formed out of which 1 leaves the cycle and and rest 5 G3P molecules get regenerated thereby regenerating 33 RuBP acceptor molecules.
