Life in the Sahara cluster around oases because it offers a supply of water.

Answer: Option C

Explanation:

Oasis gets formed when there is an availability of surface water or a source of water under the ground. Because of rock accumulation in the desert, water cannot be seen. So, oasis plays a vital role in providing food and productive growth to plants.

This also acts as a stop for traders who travel along it to fill their foods. The knowledge about the oasis locality in the desert seems to be important for exportation purposes. Eg: the oases in Ghadames, Libya.
