Explanation

Correct answer. Coelomates have a fluid filled body cavity called coelom with a complete lining called peritoneum derived from mesoderm, e.g., annelids, molluscs, arthropods, echinoderms, hemichordates, and charodates. Pseudocoelomates have a pseudocoelom which is a fully functional body cavity where tissue derived from mesoderm only partly lines the fluid filled body cavity, e.g. aschelminthes. Acoelomates have no body cavity at all, e.g., platyhelminthes.
