Correct answer

A. 2

Step-by-step solution

The number of mitochondria per cell is variable depending on the physiological activity of the cells. The cristae increase the surface area. Mitochondria are the sites of aerobic respiration. The matrix also possesses single circular DNA molecule, a few RNA molecules, ribosomes (705) and the components required for the synthesis of proteins. The mitochondria divide by fission.
