Answer 2

It is C (Oxygen).
Carbon dioxide is one of the products of the end of cellular respiration.
I don't really know much about water and nitrogen but I do know that oxygen needs to be present as a necessary reactant.

If I'm wrong, I'm sorry... But this is what I can think of...

Answer 3

It is C.

Answer 4

The equation for cellular respiration is
C6H12O6 + 6O2 → 6CO2 + 6 H2O + ENERGY
