Which of the following is a mite?

Explanation:
Mites are tiny arachnids belonging to the subclass Acari, with eight legs as adults and a body built for living on or in a host. Demodex is a genus of mites that commonly inhabits hair follicles and sebaceous glands of mammals, so it fits as a mite. The other organisms are not mites: roundworms are nematodes with elongated cylindrical bodies and a simple digestive tract; tapeworms are flatworms (cestodes) with a ribbon-like, segmented body and no digestive tract of their own; heartworms are filarial nematodes that live in the heart and pulmonary arteries. So Demodex is the correct example of a mite.
