Cestodes are categorized under which broad group of animals?

• A. Microsporidians
• B. Acanthocephalids
• C. Helminths
• D. Nematodes

Answer: (C)

Cestodes are tapeworms, which are parasitic flatworms. In lab and veterinary terminology, the term helminths is used as the broad category for parasitic worms, and it includes flatworms like cestodes and trematodes as well as roundworms (nematodes). So cestodes fit under helminths because they are part of this general worm-like parasite group. Microsporidians are unicellular parasites, not worms. Acanthocephalids are a type of parasitic worm within the broader helminth group, but they are not the umbrella category. Nematodes are another distinct group of parasitic worms (roundworms) that also fall under helminths, but the broader label that covers cestodes as well is helminths.
