Answer:
The correct answer is C. benefit ... harmed
Explanation:
Predation is a type of interaction between two individuals in which one individual gets harmed which is called prey and another organism who is predator gets benefitted.
In predation, the predator kills its prey and consume it to survive. For example, Lion is a predator and deer is the prey so during predation lion kills the deer and consume it so here lions get benefited by consuming deer and deer is harmed as it lost its life. So the correct answer is C. benefit ... harmed.
I believe the answer may be commensalism. This is a relationship between two organisms where one of the organism benefits from the relationship, but the other is neither harmed nor helped.
