Which urban growth model depicts a city with a central business district encircled by a transitional area, followed by working-class residential neighborhoods, and finally a commuter zone?

Explanation

The concentric zone model illustrates urban expansion as a series of rings radiating outward from the central business district, passing through a transitional zone, then working-class residences, and finally the commuter belt. Other models, such as the multiple nuclei and sector models, describe different urban structures.
