Solution

The correct option is D
neither photosynthesis nor respiration.

Oxygen gas comes from the oxidation of water in photosynthesis, not at all from CO2. In respiration CO2 is evolved from chemical intermediate instabilities in the TCA/Citric Acid/Krebs cycle, not from anything to do with oxygen gas.
