A. Desert

B. Savanna

C. Rain forest

D. Tundra

The correct answer is D. Tundra

Explanation:

Tundra biome is one of the coldest biomes on Earth, indeed, the temperature in this biome can be as low -50° C in some zone. At this extremely cold temperature, animals and plants have adaptations to survive in these climatic conditions. For example, animals such as the arctic hare or the polar bear that are found mainly in the tundra biome have thick fur that helps them keep body temperature despite low temperatures in their environment. Thus, the biome in which you would most likely find species adapted to extremely cold temperatures is the Tundra.
