Which of the following is NOT a domain?

Explanation:
Domains are the highest taxonomic rank for cellular life, and the three domains are Bacteria, Archaea, and Eukarya. A domain names a line of descent and a broad, distinct group of organisms. The term that is not a domain is “cell” because a cell is the basic unit of life, not a classification category. The trio Bacteria, Archaea, and Eukarya exactly names the domains. Prokaryote describes a type of cellular organization (lacks a nucleus) rather than a taxonomic rank, and virus refers to a particle that is not cellular and not assigned to a domain. So the non-domain here is cell.
