Solution

The correct option is A 1, 2 and 3 are correct
Peptidoglycan is a polymer that is present in the cell wall of most bacteria. It is also called as Murein. However, Archaebacteria are devoid of peptidoglycan in its wall. Instead, they are made up of the polysaccharide called pseudomurein. Arachebacteria consists of 3 groups, namely halophiles, thermophiles and methanogens.
Thus, the correct answer is '1, 2 and 3 are correct.'
