Which of the following best describes a functional region?

A functional region is best described as an area that is organized around a central hub or focal point, with connections that facilitate interactions and relationships within that area. This central point could be a city, a service area, or any location that serves as a point of reference for social, economic, or political activities. The interactions are often linked to specific functions, such as transportation networks, trade, or communication, which highlight the functional aspect of the region.

For example, a metropolitan area may be considered a functional region if the surrounding suburbs rely on the central city for employment, services, and amenities. The bonds of connectivity are what define the nature of the functional region, distinguishing it from other types of regions that might not have such defined interactions or organization around a focal point.
