c) The inner membrane of the mitochondria is folded to make more surface area where chemical reactions can take place. The more the folds, the bigger the surface. These folds are called cristae.

Answer:

c) The inner membrane known as the Cristae is folded. The folds of the inner membrane or the Cristae provide an increase in the Surface Area which gives the Mitochondrion more locations for ATP( the energy currency) production to occur.
