The figure below shows the structure of a mitochondrion. Select the part correctly matched with its function.

A $Part (C) : Cristae — possess single circular DNA molecule and ribosomes$
B $Part (A) : Matrix — major site for respiratory chain enzymes$
C $Part (D) : Outer membrane — gives rise to inner membrane by splitting$
D $Part (B) : Inner membrane — forms infoldings called cristae$

Solution & Step-by-step Explanation

The inner membrane of a mitochondrion forms numerous infoldings called cristae, which increase the surface area for ATP generating chemical reactions. Matrix (not cristae) contains DNA and ribosomes.
