Asseration : Archaebacteria are able to survive in harsh habitats.
Reason : Presence of peptidogly cen in wall help archaebacteria to survive in extreme conditions.

B. If both assertion and reason and true and reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.

Explanation

Archaebacteria are special since they live in some of the most harsh habitats such as extreme salty areas (halophiles), hot springs (thermoacidphiles) and marshy bacteria in having a different cell wall structure and this feature is responsible for their survival in extreme conditions. Archaebacteria are characterised by absence of peptidoglycan in their cell walls. Instead cell wall contains protein and non cellulosic polysaccharide.
