Hint:Mitochondria is called the powerhouse of the cell. Biochemical processes like respiration take place in mitochondria. It is found in all eukaryotic cells.

Complete Answer:
To answer this question, we must know about the structure and function of mitochondria.
The mitochondria are a semi autonomous body in the cell. It is a double membrane bound organelle present in multicellular organisms. The membrane of mitochondria is composed of phospholipids. The mitochondria is composed of
Outer membrane, Intermembrane space, Inner membrane, Cristae, Matrix
The mitochondria has circular DNA and has its own independent genome. Mitochondrial proteins are transcribed from the mitochondrial DNA.

Function of Mitochondria- It supplies energy to the cell. It performs other functions like signalling, cellular differentiation, cell death and also controls cell cycle and cell growth.
>Nucleus is the heart of the cell. It contains the genetic material composed of DNA.
>Chloroplast is the organelle present in the plant cell. The main function of chloroplast is photosynthesis. It contains circular DNA.
>Digestive enzymes- These are the proteolytic enzymes which degrade protein. These enzymes help in metabolism.

Thus the correct answer is (C). Mitochondria are able to produce their own protein.

Note:Mitochondria are thread-like granular structures which are present in the multicellular eukaryotic cell. They are involved in synthesis of chemical energy called the ATP. They have their own genome by which they synthesise the proteins which are required for cellular metabolism.
