Answer:
c) H₂O
Explanation:
Oxygen liberated during photosynthesis comes from water not from carbon dioxide. It was proved by using the isotope technique.
In the process of photosynthesis, light energy converted in chemical energy i.e. green plants absorb sunlight and formed the product such as glucose, water and oxygen by using the carbon dioxide and water. Photosynthesis is a multistep process not a single step process.
