Answer 1

its B. the alpine tundra occurs on mountaintops. just took the test.

Answer 2

The answer is:

B. The alpine tundra occurs on mountain tops.

If you'd like to know why:

Alpine tundra biomes are found in mountain tops, and the altitude is the reason why it is cold. Another difference between these two tundra biomes is the lack of permafrost in Alpine tundra. This allows Alpine tundra to have more plant variations than Arctic tundra but trees do not grow in Alpine tundra.

Knocking out the other choices though, there are many well-adapted animals in Alpine tundras, they do not have lower temperatures, and as mentioned before, trees cannot grow in the Alpine Tundra biomes.
