Which is wrong about mitochondria?

Correct option is D. Many circular DNA and few ribosomes are found in matrix. The mitochondrion is a double-membrane-bound organelle found in most eukaryotic organisms. Mitochondria generate most of the cell's supply of adenosine triphosphate (ATP), used as a source of chemical energy. A mitochondrion has thus been termed the powerhouse of the cell. Mitochondria contain their own genome, an indication that they are derived from bacteria through endosymbiosis. So, the correct answer is 'Many circular DNA and few ribosomes are found in the matrix'.
