Solution

The correct option is C Large ears and long legs conserve body heat.
A polar bear has a layer of fat under its skin which helps it stay warm. It also has a thick layer of fur. The wide, large paws help a polar bear to walk in the snow. When a polar bear swims under water it closes it nostrils so no water can get in. Body temperature, which is normally 37C (98.6F), is maintained through a thick layer of fur and an insulating fat layer (up to 11 cm or 4.5 in. thick).
