one benefits, one is harmed
both are harmed
both benefit
rewatch submit

Explanation:

In parasitism, a symbiotic relationship, the parasite (one organism) benefits by deriving nutrients or other advantages from the host, while the host is harmed. "Both are harmed" is incorrect (that's more like competition or amensalism), and "both benefit" is mutualism. So the correct option is the one stating one benefits, one is harmed.

Answer:

A. one benefits, one is harmed
