The domains of living organisms are-
A
Archaea, Euryarchaeota, and Eukarya, and they are the broadest level oftaxonomic organization.
B
Flustrina, Archaea, and Bryozoa, and they are the second-lowest level of taxonomic organization.
C
Prokarya, Bryozoa, and Bacteria, and they are the lowest level of taxonomic organization.
D
Archaea, Bacteria, and Eukarya, and they are the broadest level of taxonomicorganization.
Explanation: 

Detailed explanation-1: -The domain Bacteria is also possibly the largest domain, containing possibly millions of unknown and unrecorded specimens. These small, single-celled organisms live almost everywhere, and are the size of most eukaryotic organelles.

Detailed explanation-2: -The most general category in taxonomic classification is domain, which is the point of origin for all species; all species belong to one of these domains: Bacteria, Archaea, and Eukarya.

Detailed explanation-3: -There are three domains of life, the Archaea, the Bacteria, and the Eucarya. Organisms from Archaea and Bacteria have a prokaryotic cell structure, whereas organisms from the domain Eucarya (eukaryotes) encompass cells with a nucleus confining the genetic material from the cytoplasm.

Detailed explanation-4: -The three domains are the Archaea, the Bacteria, and the Eukarya. Prokaryotic organisms belong either to the domain Archaea or the domain Bacteria; organisms with eukaryotic cells belong to the domain Eukarya.
