Option 1, Fasciola, is not a tapeworm. Fasciola is actually a type of flatworm known as a liver fluke. It infects the livers of various animals, including humans.

Option 2, Schistosoma, is also not a tapeworm. Schistosoma is a type of parasitic worm known as a blood fluke. It primarily infects the bloodstream and can cause a disease called schistosomiasis.

Option 3, Taenia, is indeed a tapeworm. Taenia species are commonly known as beef or pork tapeworms. They are parasites that live in the intestines of mammals, including humans. Ingesting the eggs of these tapeworms can lead to an infection called taeniasis.

Option 4, Enterobius, is not a tapeworm. Enterobius is a type of roundworm known as the pinworm. It is a common human parasite that lives in the intestines and can cause itching around the anus.

Therefore, the correct answer is option 3, Taenia.
