Hint: Archaebacteria range from different bacteria (eubacteria) in having a different cell wall structure and this characteristic is reason for their survival in intense conditions.
Complete answer:To answer this question, at first, we have to know the difference between archaebacteria and eubacteria. Archaebacteria typically have the identical shape, size, vitamins and look like microorganisms (bacteria). They multiply by using binary fission. However, archaebacteria cell walls do not comprise peptidoglycan. They additionally have an exceptional membrane lipid bond as compared to the bacteria and eukarya. Archaeal membrane lipids have ether bonds whereas microorganisms like bacteria has ester-related lipids.

Now lets us find the solution from given options -
The cell wall of archaea consists of S-layers and lacks peptidoglycan molecules with the exception of methanobacteria who have pseudopeptidoglycan in their cell wall. Eubacteria are enclosed by a cell wall. The wall is made of cross-connected chains of peptidoglycan, a polymer that mixes amino acids and sugar chains.
Rather than having one primary set of adaptations that works for all environments, Archaea have developed separate protein functions that are adapted for each environment. These archaebacteria and eubacteria can live in excessive salt concentration, excessive temperature, excessive pressure etc.
Additional information: The 16S rRNA gene is used for phylogenetic research as it is highly conserved among extraordinary species of microorganisms like bacteria and archaea. Botharchaebacteria and eubacteria have genetically extraordinary 16S rRNA.
Thus, the right answer is, ‘All of the above’.
Note:The mode of reproduction, food and cellular structure of archaebacteria resembles a regular eubacteria. Their cell walls, composed of a few polymers, however do not consist of peptidoglycan unlike eubacteria. Lipids in their cytoplasmic membranes are ether connected unlike eubacteria which comprise glycerol ester lipids of their cell membrane.
