Solution

The correct option is D lack peptidoglycan in their cell wall
Thermococcus and Halobacterium are archaebacteria. Unlike eubacteria, the cell wall does not have peptidoglycan. These are prokaryotes and hence lack membrane bound cell organelles. They live in extreme environmental conditions. They have 70S ribosomes.
