Explanation:

Austria, Switzerland, Liechtenstein, and South Tyrol (a region in Italy) are all in the Alpine region. The Alpine mountains are a key geographical feature shared by them. Coastal beaches (not in these areas), tropical rainforests (not in these temperate regions), and deserts (not in these alpine/temperate zones) don't fit.

Answer:

Alpine mountains
