Why the answer is C, and why the others tempt you.
Desertification in the Sahel is caused by human activities such as overgrazing, deforestation, and over-cultivation, compounded by prolonged drought and declining rainfall — not by increasing rainfall. Increased annual rainfall would actually reduce desertification by promoting vegetation growth. Options A, B, and D are all recognised drivers of desertification in the region.
