The correct answer is:

C.One kind of organism is being helped, but the other one is not harmed or helped.

In commensalism, one organism benefits from the relationship, while the other is neither helped nor harmed. This type of interaction is neutral for one organism and beneficial for the other.

Here's an explanation of the other options:

A.Two different kinds of organisms harming each other.

This describes a competitive relationship or antagonism, where two organisms are competing for the same resources and harm each other in the process. In this type of relationship, both organisms are negatively affected. This is the opposite of symbiosis, because, in a symbiotic relationship, at least one organism benefits, and in this case, both are harmed.

B.Two different kinds of organisms are neither helping nor harming each other.
