Confusing if mucopeptide is synonmous with Peptidoglycan cell wall .
Anyway I will go for C

In this question I think choice A is correct. Actually I was mislead by the word "mucopeptide ".I thought it might not be peptidoglycan but in fact
Mucopeptid cell wall = peptidoglycan cell wall.
So I admit my "ignorance of knowledge " about it
Best of luck
