Adaptation is the ability of an organism that allow to survive and thrive in the changed environment. Structural adaptations are physical features of an organism that adapted through time. Tundra organisms have developed specific adaptations which allow them to cope up with the extreme climate of the tundra. The adaptations include thick fur, dense hair, and retention of dead leaves. Insects such as mosquitoes survive in extremes tundra climate by converting the water in their bodies to glycerol, a chemical that acts like antifreeze.

It would be D. because thick fur and dense fur are the same and keep the animals warn. production does not help prevent heat loss.  :)
