Which of the following is true about a clustered settlement?

A clustered settlement is characterized by buildings that are located closely together. This arrangement often arises from the natural development of a community where residents are drawn to live in close proximity for reasons such as social interaction, ease of access to resources, and shared services. In many cases, clustered settlements facilitate more efficient use of land and infrastructure, such as water supply, sewage systems, and transportation networks, which further contribute to their sustainable development.

The other options do not accurately represent the nature of clustered settlements. Isolated buildings would imply a dispersed settlement pattern, which contradicts the definition of clustering. A singular architectural style is not necessarily a requirement of clustered settlements, as they can feature diverse designs reflective of various periods or cultural influences. While tourism might occur in some clustered settlements, especially in picturesque or historically significant areas, it is not a defining characteristic of clustered settlements overall. Therefore, the understanding of clustered settlements hinges on the density and proximity of the buildings themselves.
