My query is from Basis of Classification in Animals topic in portion Animal Kingdom of Biology – Class 11

Answer 1

The correct choice is (c) Mesoderm holds the internal organs in its own place

To elaborate: Body cavity is absent in acoelomates. In this type of animals, mesoderm helps in holding the internal organs in its own place. Coelenterates, platyhelminthes and porifera are the best examples for acoelomates.
