Solution

The correct option is C Mucopeptide
Both Gram negative and Gram positive bacteria have a peptidoglycan layer in the cell wall. The peptidoglycan in Gram negative bacteria is present in the periplasmic space. Apart from this, Gram negative bacteria have an outer wall made up of lipopolysaccharide. Peptidoglycan is also called as mucopeptide. It is a polymer that is made up of sugars and amino acids.
Thus, the correct answer is 'Mucopeptide.'
