Answer :
C. Adaptation
Adaptation is a physical characteristic that helps an organism survive in an environment. The answer is not population because a population is a group of organisms of the same species in an area. It's not evolution because evolution is the process that brings about favorable adaptations. It's not ecosystem because an ecosystem is an environment where the populations interact. Adaptation is the clearest correct answer, because an adaptation is a physical structure.
