In which type of rural settlement dwellings are built in close vicinity ?

Correct option is D

In compact rural settlements, dwellings are built in close proximity to each other. This type of settlement is characterized by homes being located near one another, often for reasons such as security, social cohesion, or limited building space. Compact settlements are in contrast to scattered settlements, where homes are spread out over a larger area, and linear and circular settlements, which are defined by their specific shapes or patterns of houses along roads, rivers, or in a circle around a central point.
