Solution

The correct option is C
Energy

Excretion means getting rid of the metabolic wastes in the body. In the process of respiration which takes place in all body cells, glucose and oxygen are the reactants and $C O_{2}$ and $H_{2} O$ are the products. These two compounds are carried by the blood to the lungs to be excreted during exhaling.
