Solution

The correct option is D Polymer of sugars.
Bacteria belong to group Monera. Organisms belonging to group Monera are primitive, unicellular and prokaryotes. They possess cell wall made up of peptidoglycan, which is in turn made of derivatives of sugar as N- acetylglucosamine and N- acetylmuramic acid, which are covalently attached to the core protein. Hence, it is a polymer of sugars. Thus, the correct answer is option D.
