L. Wirth is known for which concept?

Correct option is B

The correct answer is: (b), Rural Urban Continuun
Louis Wirth, an American sociologist, is known for his influential work on urban sociology, particularly his book "Urbanism as a Way of Life," published in 1938. While Wirth's research covered various aspects of urban life, he is often cited in discussions about the rural-urban continuum.
The concept of the rural-urban continuum describes the gradual transition and interdependence between rural and urban areas. Rather than viewing rural and urban areas as distinct and separate entities, the rural-urban continuum perspective acknowledges the complex and fluid nature of human settlements along a continuum.
Wirth's studies on urbanization and the social dynamics of cities contributed to our understanding of how urban and rural areas are interconnected and how they influence each other. His work highlighted the similarities and differences between urban and rural life and emphasized the ongoing exchange of people, resources, and ideas between rural and urban areas.

Primate city: The concept of primate city was developed by Mark Jefferson in 1939. It is based on the observation that the country’s leading city is usually disproportionately larger than others in the system.
Central place: central place theory is an attempt to explain the spatial arrangement, size and number of settlements. The theory was originally published in 1933 by a German geographer Walter Christaller who studied the settlement patterns of Bavaria, Southern Germany.
Conurbation: The term conurbation was coined by Patrick Geddes to describe a built up area created by the coalescence of once separate urban settlements, initially through ribbon development along the main inter- urban routes.
