The correct answer is "a change in way of life that allows people to survive in a particular environment." This is because adaptation refers to the process of adjusting or modifying one's behavior, practices, or physical characteristics in order to better fit or survive in a specific environment. It involves making changes to one's way of life, such as hunting strategies, clothing, shelter, or farming techniques, to suit the conditions of a particular habitat. Adaptation is crucial for the survival and success of a species in its environment.
