Which would be classified as an ectoparasite?

Explanation:
Ectoparasites live on the outside of the host and feed from it. The flea fits this perfectly: it spends its life on the animal’s fur or skin, biting and sucking blood, which makes it an external parasite. In contrast, tapeworms and roundworms live inside the host’s body, as internal parasites (endoparasites). A mosquito larva grows in water and is not parasitic on the host at that stage, so it isn’t an ectoparasite.
