The correct answer is B) Proteins.

Mitochondria contain their own DNA and ribosomes, enabling them to synthesize some of the proteins they need for their function. This makes them semi-autonomous organelles.

Mitochondria are often called the “powerhouses” of the cell because they generate most of the cell’s supply of adenosine triphosphate (ATP), used as a source of chemical energy. They are believed to have originated from symbiotic bacteria, which is supported by the presence of their own DNA (circular, similar to bacterial DNA) and ribosomes (70S, similar to bacterial ribosomes).
