C Correct answer
Explanation

Cellular respiration is the process by which cells break down glucose in the presence of oxygen to produce usable energy in the form of ATP. Photosynthesis builds glucose rather than breaking it down, and mitosis is cell division. Fermentation also breaks down glucose but is an anaerobic process that yields much less energy than aerobic respiration.
