D Correct answer
Explanation

Each mitochondrion is bound by a double membrane. The outer membrane is smooth and straight, while the inner membrane is thrown into numerous folds called cristae. Thus, the surface area of inner membrane is much higher than the outer membrane. The cristae bear numerous, minute, regularly spaced particles called elementary particles or oxysomes. Mitochondria are able to change shape and even move to the areas where considerable activity is taking place. This is facilitated by cytoplasmic streaming movement.They are known as the powerhouse and ATP mill of the cell.
