What is the function of central business districts (CBD)?

The function of central business districts (CBDs) is best described by the characteristics of high land values and a concentration of offices and commercial activities. CBDs serve as the economic hubs of cities, where significant business transactions take place, and they typically host a variety of services such as retail shops, restaurants, and banks. The high land values in these areas are driven by the demand for prime locations that facilitate access to a high number of customers and business opportunities.

This concentration of economic activity also influences the urban layout, with tall office buildings and significant infrastructure supporting the business sector. The presence of various amenities and public transport links further enhances the attractiveness of CBDs as locations for both businesses and consumers.

In contrast, the other options describe areas with different characteristics and functions. Residential areas usually reflect lower land values to accommodate more housing, while districts known for parks and recreation prioritize green space and leisure over business activities. Urban farms and community gardens focus on agriculture and food production, which is not the primary function associated with CBDs.
