Answer:
The correct answer is D. The geographical feature that contributed North Africa to develop so differently from southern Africa is the Sahara Desert.
Step-by-step explanation:
The Sahara Desert is the largest desert in the world. It is located between the Sahel and the Mediterranean, and its climate affects the peoples that have historically developed within it.
Its arid, dry and hot climate gives rise to an almost absolute lack of vegetation, with abundance of sand and dunes. As a consequence, the villages that settle there must deal with droughts, lack of rainfall, difficulties in cultivation, and an overpopulation near areas near rivers, lakes or seas.
