These are archaebacteria which can tolerate high temperature.

Correct Option: A

These are archaebacteria which can tolerate high temperature.

Archaebacteria differ from other bacteria in having a different cell wall structure. They lack peptidoglyan in cell wall and possess a monolayer of branched fatty acids attached to glycerol by ether bonds in their cell membranes.
