Answer:
B) desalination.
Explanation:
One way that wealthier more urbanized countries like Saudi Arabia have dealt with the lack of freshwater is through desalination. Lack of fossil water is a problem for countries in the drier climates of North Africa and Southwest Asia. Some countries, especially Saudi Arabia, have begun creating solar powered desalination plants to create fresh water to sustain their growing population. Poorer countries do not have the money or technology to support this so populations cluster near the rivers.
