The correct option is (A) Lochotrophozora.
Annelids, mollusks, bryozoans, brachiopods, platyhelminthes, and other creatures that descended from these organisms' common ancestor are included in the monophyletic group of animals known as Lophotrochozoa.
What is Lophotrochozoa?
- According to the definition given in 1995, the term "Lophotrochozoa" refers to the "last common ancestor of the three classic lophophorate taxa (brachiopods, bryozoans, and phoronid worms), the mollusks, and the annelids, as well as all of that common ancestor's offspring." Â
- The affiliation of spiralian groups not specifically mentioned in the definition to Lophotrochozoa depends on the topology of the spiralian tree of life, and in some phylogenetic hypotheses, Lophotrochozoa may even be synonymous with Spiralia.
- This is because the definition is cladistic (a node-based name). The Lophotrochozoa includes the more derived Lophophorate, Nemertea, and Annelida families as well as the Cycliophora and Mollusca basal groups.
