What is Cellular respiration?

Energy is the ability to perform a job or to produce heat. Chemical reactions involve a rearrangement of atoms between substances with rupture or formation of chemical bonds and this generates changes in the energy of the system.

An exothermic reaction is one where energy is released from the system into the environment in the form of heat.  

Cellular respiration is carried out in the mitochondria of the cells. There the oxygen absorbed from the external environment is combined with carbohydrates (raw material) to release the chemical energy they contain. Water vapour and carbon dioxide are also released.

Thus, option "A" is correct.
