The right answer is Bacteria and Archaea.
A prokaryote is a unicellular organism (bacterium, cyanophyceae) that does not have a nucleus. The DNA is circular, usually unique and grouped in a nucleoid. This region contains the genetic material, but is not separated from the rest of the cell. This is precisely what separates the prokaryote from the eukaryote.
Archaea are prokaryotic unicellular microorganisms. Archaea, which often look like bacteria, have long been regarded as specific extremophile bacteria, until phylogenetic research on prokaryotes, begun in 19652, culminated in the publication in 1977 of a phylogenetic tree based on the sequences of the ribosomal RNA genes of the organisms studied, a tree in which the prokaryotes were split into two distinct domains, that of the bacteria and that of the archaea.
