Answer:
The Sahel is region A.
Explanation:
The Sahel is a region that stretched in a roughly east to west direction, located just below, or rather just south of the Sahara Desert. The Sahel is a semi-arid region, acting as a transitional zone between the desert and the savanna. This relatively narrow (for African standards) region stretches from the Atlantic coast to the Indian Ocean coast.
There are a total of ten countries where the Sahel occupies territory, with some countries having a larger share, while some very small ones. Even though the region is semi-arid, in the areas where there are rivers, it is actually offering very conditions for agriculture, and more and more people have been using this. Another important thing that needs to be mentioned about the Sahel is that it is the region in which the Great African Wall is being created, which is an attempt to make this region forested and prevent desertification, which also brings is economic benefits and a better life for the people in the region.
