Which parasites live internally?

Explanation:
Endoparasites are parasites that live inside the host’s body, whether in the gut, tissues, or organs. This internal residence is exactly what “live internally” describes. Examples include intestinal worms like roundworms and tapeworms, and protozoa such as Plasmodium or Giardia. In contrast, ectoparasites stay on the outside of the host (skin, fur, feathers), parasitic plants obtain nutrients from other plants rather than animals, and facultative parasites are organisms that can live freely but may become parasitic under certain conditions. So, the option that best fits “live internally” is endoparasites.
