Answer: The correct answer is- C.Predator-Prey.
Parasitism can be described as a type of biological interaction between two species where one organism lives on the surface or inside the body of another organism in order to complete its life cycle and get essential nutrients. This organism is called parasite and the other is called host. The host is harmed by the parasite.
This is a type of prey- predator relationship as a prey is captured by predator as a food source and therefore, predator is benefited whereas prey is harmed.
