<h3>What are parasites?</h3>
Parasites may be defined as the types of living organism that significantly lives on or in a host organism and gets their food from or at the expense of its host. There are three main classes of parasites that can cause disease in humans: protozoa, helminths, and ectoparasites.
An ectoparasite is a group of parasites that would you choose to study because these parasites live on the external surface of the hosts. So, they are easy to recognize as compared to endoparasites. Some examples of these parasites may include fleas, lice, Nonogenea, Copepoda, etc.
Therefore, among the options given, an ectoparasite is a group of parasites that would you choose to study. Thus, the correct option for this question is A.
