Answer:
C)
Explanation:
Bacteria are prokaryotic, which means they (generally) don't have organelles or a nuclear envelope around their nucleus. They have ester linkages in the phospholipids in their cell membranes, while archea, which are also prokaryotic, have ether linkages. Ether linkages are more chemically stable than ester linkages, and since archea live in extreme environments this is helpful.
Bacteria are not multicellular and do not have organelles (complex cellular structures) besides ribosomes.
