None of the above

Detailed explanation-1: -To increase the capacity of the mitochondrion to synthesize ATP, the inner membrane is folded to form cristae. These folds allow a much greater amount of electron transport chain enzymes and ATP synthase to be packed into the mitochondrion.
Detailed explanation-2: -Mitochondria have two membranes: an outer and an inner membrane. The outer membrane separates the mitochondria from the rest of the cell. The inner membrane is elaborately folded and the folds – called cristae – create a larger space to accommodate all of the protein machinery involved in producing energy.
Detailed explanation-3: -A crista (/ˈkrɪstə/; plural cristae) is a fold in the inner membrane of a mitochondrion. The name is from the Latin for crest or plume, and it gives the inner membrane its characteristic wrinkled shape, providing a large amount of surface area for chemical reactions to occur on.
Detailed explanation-4: -Cristae are folds in the inner mitochondrial membrane. Mitochondria are organelles in eukaryotic cells. The major function of cristae is to increase the surface area of the mitochondrial membrane. This allows membrane processes to produce more energy at a faster rate.
