Answer 1

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.
