Solution

The correct option is B Mesosomes
In prokaryotes mesosome is convoluted membranous structure which is formed due to the invagination of plasma membrane.

They increase the surface area of the plasma membrane to carry out various enzymatic reaction. They also help in DNA synthesis and replication of cell wall. They help in bacterial respiration and secretion process.

Since mesosomes helps in respiration which is performed by mitochondria in eukaryotic cells they are analogous to mitochondial function.
