The two most important factors which account for the pattern of population distribution in West Africa are
Economic prosperity and regional migration
Economic prosperity and favourable physical conditions
Favourable physical conditions and human inertia
Historical antecedence and regional migration
Correct answer is C
Physical conditions determine the population distribution in Africa. The topography of an area, how favourable it is determine population distribution. People tend to move from a place to another if the condition is not favourable. Nomads for example move their cattles around for pastures to graze.
