Q. Which one of the following term characterizes the interaction between herpes simplex virus and a human?

Correct Answer: c) Parasitism

Explanation:
– Herpes simplex virus (HSV) benefits by using the human host’s cells to replicate, while the host is harmed (e.g., lesions, disease). This one-benefits/one-harmed relationship is called parasitism.
– Symbiosis (and endosymbiosis) usually implies a mutually beneficial or at least neutral long-term association, which is not the case here.
– Endoparasitism is a subtype of parasitism where the parasite lives inside the host. While HSV does live inside host cells (so it is an endoparasite), the standard term that characterizes the interaction itself is parasitism.
