Solution
The correct option is B A-Annelids, Echinoderms and Chordates; B-Aschelminthes
The body cavity present between the intestinal canal and the body wall in animals is called the coelom. The type of coelom in figure A is a true coelom and is usually found in annelids, echinoderms, arthropods, and chordates. The type of coelom shown in figure B is a pseudo-coelom and is found in roundworms or Aschelminthes. Thus, the correct answer is 'A-Annelids, Echinoderms and Chordates; B-Aschelminthes.'
