Roundworms

• A. Roundworms
• B. Hookworms
• C. Tapeworms
• D. Whipworms

Answer: (A)

Roundworms are a broad group of nematodes, which are long, cylindrical, non‑segmented parasites with a complete digestive tract. In veterinary parasitology, “roundworms” is the umbrella term for many common intestinal parasites, including species like Toxocara and Ascaris, that inhabit the digestive system of hosts. Tapeworms are not in this group; they’re flat, ribbon‑like cestodes with a different body plan and life cycle. Hookworms and whipworms are also nematodes, but they’re specific types within the roundworm family, each with unique mouthparts and lifecycles. So naming the general category that covers these organisms, roundworms, is the most appropriate label for this concept.
