Polar bears maintain homeostasis in freezing cold weather primarily through their thick fur, which retains heat. Additionally, they have a thick layer of blubber beneath their skin that provides insulation and energy reserves. While their metabolism does play a role in generating body heat, the most significant factor in keeping them warm in extreme cold is their fur and blubber layer. Therefore, the best response from your options is: "Their thick fur retains heat."
