Solution
The correct option is C Bacteria Peptidoglycans (or mucopeptide or glycopeptide or murein) are the structural elements of almost all bacterial cell walls. They constitute as much as 95% of the cell wall in some Gram-positive bacteria to as little as 5 to 10% in Gram-negative bacteria. Peptidoglycans are made up of a polysaccharide with muramic acid and glucosamine residues in equal amounts.
