Polar bears who have white fur and live in the Arctic must use "camouflage".

Option: C

Explanation:

The Arctic seems to have small amount of rainfall, with windy and cold weather. Here in  the Arctic, plants sometimes develop very near to the ground and have small leaves. This enables preserve water and prevent damage from the wind. Polar bears are well designed for Arctic sustainability. Their adaptations involve: A white look-as a camouflage from the snow and ice predators, Thick fat and fur coats-for cold insulation, A thin volume-to-volume surface-reducing heat loss and a big feet-to spread their load and grasp the ice more.

Polar bears who have white fur and live in the Arctic must use camouflage adaptation.

Explanation:

The white furs of polar bear is there so that they camouflage the snowy environment of arctic.

The white fur is confused with snow by predators.  Also, the thick fat layer is for insulation and keeping itself warm in cold habitat. These features of polar bear are an example of natural habitat adaptation.

Apart from this they have greasy body surface that does not sustain water to their body and the wide feet are for better grip to walk on ice.

Polar bears have evolved from the brown bears and got geographically separated and modified itself to arctic region climate.

The blending with the environment caused polar bears best adapted for the environment and hence evolution.
