Explanation:

Oases are defined as areas in deserts with a water source that allows vegetation to grow. Option A is incorrect as sandstorms are not characteristic of oases. Option C is wrong because oases are not defined by gold mines. Option D is incorrect as oases are not specifically about cacti groups but about water - supported vegetation.
