b) close to water

People in the northern countries of Africa live close to water.

Explanation:

The world's largest desert 'Sahara' has spread over most countries in the north of the African continent. This region is characterized by extreme scarcity of water. The population in these countries is concentrated only in places where there is the availability of water. Compared to the total area, the population in these countries is extremely scarce. Lack of vegetation and a hot, dry climate all throughout the year make living really tough.
