Answer:
Correct Answer: B
Solution:
Nematodes, commonly called round worms, constitute the largest phylum nematoda of super phylum Aschelminthes.
They are distinct from flatworm and tapeworms (platyhelminthes), in having a cylindrical body, a pseudocoel, and a complete digestive tract lined by endodermal epithelium.
Majority of nematodes are free living but most of the flatworms are parasitic.
