Correct Answer: Option (B) — Lake Faguibine

Concept & Option Breakdown

Standard Reference Verified

Lake Faguibine in northern Mali (West Africa) was once one of the largest lakes in the region, fed by floodwaters from the Niger River. Due to prolonged droughts since the 1970s and climate change, it has almost completely dried up and turned into dry land/desert.

Elimination Heuristic & Exam Approach

Lake Victoria is in East Africa; Lake Volta in Ghana remains a massive reservoir; Lake Oguta in Nigeria is a permanent lake.
