please select the best answer from the choices provided

Explanation:

Alpine tundra is located on mountaintops. Both alpine and arctic tundra lack trees (so option a is wrong). Both have animal life (so option c is wrong). Arctic tundra can have very low temperatures too, and temperature isn't the main distinguishing factor. The key difference is the location - alpine on mountaintops.

Answer:

B. The alpine tundra occurs on mountaintops.
