Answer:
B. the Sahel
Step-by-step explanation:
The Sahel is the strip of the land and region of central-western Africa. It consists of the area between Sahara on the North and the savanna on the south. It goes through several African countries – Algeria, Mauritania, Central African Republic, Nigeria, Mali, Niger, Cameroon, Burkina Faso, Chad, Senegal, Sudan, South Sudan, Ethiopia, and Eritrea.
It has a dry, tropical climate with winds throughout the year, a bit milder than Sahara. There is not much flora because of the dryness of the land, and it is mostly rich in livestock.
