Which one of these words (ocean, canyon, plateau, mountain) goes with desert, rainforest, and ravine?

Desert, rainforest, and rain are places that can have its own weather conditions and are not elevated highly from the ground.  Desert for instance is usually a hot place since it doesn’t have anything to shield the sun rays. Rainforests also can have its own weather because of the surrounding plants and trees, and also ravine, which is usually the same as canyon but narrower. So the answer would be plateau.

a and b because with the other three, they simplify to something else.
