Which statement describes archaeal cell wall composition?

Explanation:
Archaeal cell walls are built from materials other than bacterial peptidoglycan, often using pseudopeptidoglycan with different sugars and linkages or relying on protein-based S-layers. Because of this fundamental difference, archaea do not have peptidoglycan in the same form as bacteria. The best description, then, is that they lack peptidoglycan in their cell walls. They do not rely on cellulose, which is typical of plants and some algae, nor on chitin, which is common in fungal walls, so those options don’t fit archaeal biology.
