B. Person's blue eyes

Explanation:

In order for organisms to thrive in the environment, they have to undergo some changes. This process is called "adaptation."

A. The arctic rabbit's white fur is its adaptation to the cold environment in the Arctic area. Thus, this is adaptation.

B. A person's blue eyes doesn't have to do with adaptation; rather, it is connected to "genetics." Such genetic information is being carried by an individual from his/her parents. This makes it the only choice that is not an example of an adaptation.

C. The giraffe's long neck is its adaptation to eating from the treetops since it is a herbivore. This also prevents it from competing with other animals for food.

D. Bears hibernating is a proof of their adaptation to the winter season. Since food is scarce on these months, the bears try to sleep in order to stay alive. This also allows them to stay warm as well.
