Which of the following is also known as a roundworm?

Explanation:
Roundworms are nematodes. They are cylindrical, unsegmented worms with a rounded cross-section, which is why people call them “roundworms.” This group (Nematoda) has a full digestive tract and a protective cuticle around a fluid-filled pseudocoelom, features that set them apart from other helminths. Trematodes and cestodes are flatworms (flukes and tapeworms, respectively), and acanthocephalans are a different kind of parasite with a distinctive spiny proboscis. So the term that corresponds to the roundworm is the nematode.
