Solution

The correct option is B Prevent heat loss from the body
Animals in polar regions have a lot of adaptations that help them withstand an extremely cold climate. A Polar bear has a thick fur and a thick deposit of fat under its skin. This gives it protection from the freezing cold. This thick deposit of fat is called blubber.
