Which parasite is known as roundworms?

Explanation:
Roundworms are nematodes, a group of elongated, cylindrical, non‑segmented worms. The common name “roundworms” is used to describe this entire phylum, which includes species like Toxocara and Parascaris that infect dogs, cats, and horses. This term highlights their round, tubular body shape, distinguishing them from other parasite groups: tapeworms are flat and segmented, while whipworms and hookworms are different nematodes with distinctive mouthparts or body shapes. So, using the familiar label for the broad nematode group is why roundworms is the best answer.
