I’m really stuck on this question. If you can help, that would be great. Question and multiple choice answers are in the picture.

Coevolution.

Explanation:

Coevolution is the process of reciprocal evolutionary change that occurs between pairs of species or among groups of species as they interact with one another. The activity of each species that participates in the interaction applies selection pressure on the others.

An example is the coevolution of flowering plants and associated pollinators (e.g., bees, birds, and other insect species).
