A. A thick layer of fat for insulation
Explanation:
Taiga is one of the world's coldest biomes. It includes the Canadian and Alaskan regions.

The mammals will be protected from the harsh winter environment and cold water by a thick layer of insulation. It will aid in the maintenance of homeostasis in mammals.
