Answer:

A. Both are unicellular organisms that lack a membrane-bound nucleus.

Explanation:

Bacteria and archaea are both prokaryotes. Prokaryotes are always single celled organisms. They also do not have a defined-nucleus. These features differentiate them from eukaryotes, which all have a membrane-bound nucleus. Some eukaryotes are also multicellular (but not all)
