The correct option is B Occupation
By analysing the land use pattern and the topography of the area, we can conclude the primary occupation of the people living there. Occupation can be inferred by using many other factors other than the topography of the land. By looking at the size of a settlement, we can determine the other activities that people might be engaged in. A large town must have people engaged in various activities like business, retail, government services, and other public services.
