Solution

The correct option is D
Cristae

The mitochondrion is a double membrane-bound organelle. It consists of an outer membrane and an inner membrane. The inner membrane has folds called CRISTAE, which provides an increase in the surface area. This allows a greater space for processes that happen across this membrane such as ATP synthesis.
