A. because of the lack of available water resources in the region

The Sahara desert is a harsh, arid environment with limited water sources. The Nile River and the Mediterranean coast provide essential water resources for agriculture, drinking water, and other basic needs. Living near these water sources allows people to have access to water for themselves, their livestock, and their crops, making these areas more suitable for human habitation.
