Solution

The correct option is A A white fur, fat below skin, keen sense of smell
Animals like polar bears in the polar regions may have the following adaptive features:
1) Low surface area to volume ratio
2) Small extremities to reduce heat loss - shorter ears and limbs
3) A thick layer of body fat/blubber - present in seals to reduce body heat loss.
4) Thick camouflaged fur
5) Thick fur on paws
So, the answer is A.
