Final answer:
People living in the Sahara region of Africa often experience shortages of clean drinking water due to limited water sources.
Step-by-step explanation:
People living in the Sahara region of Africa often experience shortages of clean drinking water due to limited water sources (option b). The Sahara region is characterized by arid and dry conditions, with little rainfall, few rivers or lakes, and lack of accessible underground aquifers. These factors make it challenging to obtain a sufficient and reliable supply of fresh water for drinking purposes.
The scarcity of water in the Sahara region is further exacerbated by population growth and climate change, which contribute to the worsening water crisis. As a result, many people in the Sahara face difficulties in accessing clean drinking water.
