Final Answer :
A
Explanation :
Parasitism is a relationship in which one species (the parasite) benefits while the other species (the host) is harmed. The parasite obtains its nourishment by living on, in, or near the host over an extended period of time. This is different from predation, where one species (the predator) kills and eats another species (the prey), and from competition, where two or more species compete for the same limited resource. Mutualism is a relationship where both species benefit.
