Answer:
d. Luke.
Step-by-step explanation:
Luke, is the only character who is not an adult. Luke has just been born, so Luke's adaptation is an intrinsic feature of his growth. As Luke grows up, he will adapt to the environment, the people, the weather, among other things. The characters who are adults have already gone through this process of adaptation and also no longer have a physical growth.
For this reason, we can conclude that the individual who will have growth as the most characteristic mode of adaptation is Luke.
