Answer:
The correct answer will be option-D
Explanation:
The process of photosynthesis release oxygen from the plant which is used by the organism on earth during cellular respiration.
The oxygen released by the plants is formed through the splitting of water molecules as a result of the transfer of electrons through the electron transport chain in the thylakoid membrane during the light-dependent reaction.
Since the released oxygen is the result of the light-dependent reaction and not the light-independent reaction or Calvin cycle where heavy oxygen isotope is utilized in the cycle.
Thus, option-D is the correct answer.
