Detailed explanation-1: -The correct option is C Cristae. Mitochondrion is a double membrane-bound organelle. It consists of an outer membrane and an inner membrane. Mitochondrial cristae are folds of the inner membrane that increase the surface area.

Detailed explanation-2: -The inner membrane of the mitochondrion folds inwards, forming the cristae. This folding allows a greater amount of membrane to be packed into the mitochondrion. The data in this study demonstrate that subunits e and g of the mitochondrial ATP synthase are involved in generating mitochondrial cristae morphology.

Detailed explanation-3: -The inner membrane of mitochondria throws itself into many folds. These folds are known as cristae.

Detailed explanation-4: -The inner membrane forms a number of infoldings in mitochondria. These infoldings are known as cristae. These are formed towards the matrix. They increase the surface area for enzyme action.

Detailed explanation-5: -Mitochondria are known as the powerhouse of eukaryotic cells. Energy production occurs in specific dynamic membrane invaginations in the inner mitochondrial membrane called cristae.
