Answer

Answer:

B. blubber

Brief Explanation:

Blubber is a thick layer of fat that insulates polar bears, helping them maintain a constant internal temperature in cold - weather. The other options are not the main adaptation for thermal homeostasis. Three - layer fur helps but not as significantly as blubber. Finding shade underground is not typical behavior for maintaining warmth in cold weather, and white skin is more for camouflage than thermal regulation.
