The correct answer is option C which is hydrogen of water is separated from oxygen.
<h3>Explanation:</h3>
Cellular respiration is the process of converting complex compounds like carbohydrates into simpler one like CO2 and water in the presence or absence of oxygen producing energy.
So water is produced by the combination of hydrogen and oxygen.
And chemical energy stored in food is also used by the cell to produce ATP.
Hence third statement is not related to respiration.
