Which parasite is an arthropod?

Explanation:
Otodectes cynotis is the parasite that fits as an arthropod. Arthropods are characterized by an exoskeleton, a segmented body, and jointed appendages. Mites, like this ear mite, are arachnids, a subgroup of arthropods, and adults typically have eight legs. The other parasites listed are not arthropods: Dirofilaria immitis is a nematode (roundworm), Dipylidium caninum is a cestode (tapeworm), and Fasciola hepatica is a trematode (fluke). These are helminths without jointed limbs or an exoskeleton, so they do not belong to the arthropod group.
