A. A - Pseudocoelomate; B - Coelomate, C-Acoelomate

B. A - Coelomate, B - Pseudocoelomate, C- Acoelomate

C. A - Coelomate; B- Acoelomate; C - Pseudocoelomate

D. A - Coelomate; B- Acoelomate; C-Eucoelomate

Correct Answer :

B. A - Coelomate, B - Pseudocoelomate, C- Acoelomate


Acoelomates : The animals which do not have coelom e.g., sponges, coelenterates, ctenophorans and flatworms. Pseudocoelomates : Body cavity is not lined by mesoderm continuously, but it is present as scattered pouches in between the ectoderm and endoderm. Aschelminthes (round worms) are pseudocoelomates. Eucoelomates (Coelomates) : The animals which possess true coelom. True coelom is found in annelids, echinoderms and chordates.
