Solution

The correct option is C Assertion is correct but Reason is incorrect.
The cell wall in the bacteria is composed of peptidoglycan which is a complex mucopolysaccharide. The polysaccharide contains the alternating N-Acetylmuramic acid (NAM) and N-acetylglucosamine (NAG) residues. These residues are a part of the mucopolysaccharides. The network of these acids are responsible for the mechanical support to the cell structure.
Thus, the correct answer is option C.
