Concept:The area marked E lies in the groundnut-producing belt of northern Nigeria.
Explanation:The map shows Nigeria, and the area marked E is around Kano State in the far north.
This region has a dry, tropical climate with a distinct wet and dry season.
The sandy soils and moderate rainfall in the area are highly suitable for groundnut cultivation.
