Answer:
A) to find flat areas of land for building
Explanation:
Topography maps show the elevation of the terrain and how flat a terrain is. Malls are usually very large buildings that occupy a large piece of land, and terrains with varying altitude increase the building costs of any type of structure.
If someone wants to build a large mall (that includes many parking spaces), they must look for some lot that is flat or can be flatten out easily.
