A) Arthropoda
B) Annelida
C) Mollusca
D) Aschelminthes
Correct Answer: D
Solution :
The members of Aschelminthes posses a false body cavity or pseudocoelom. The pseudocoelom develops from blastocoel and is not lined by peritoneum. In Arthropoda and Mollusca the actual or true coelom is reduced but spaces between viscera grow and form a large cavity filled with blood. Its called haemocoel. Annelids are coelomate. The coelom is formed by the splitting of mesoderm. Therefore, it is schizocoel.
