The correct answer is Option 2. Explanation & Key Takeaways: • Dispersed settlements are characterized by isolated houses rather than being clustered into a single area. • The following points are relevant to dispersed settlements: • (a): Found in hilly areas, grasslands, and dense forests due to unfavorable physical and environmental conditions. • (b): The structure of houses in dispersed settlements is isolated, far from one another. • (c): While natural and man-made features like rivers, mountains, roads, and railway lines can influence the spacing of houses, in the Indian context this is not a primary factor for their dispersion. • However, (d) is incorrect as dispersed settlements are not commonly found in plains and fertile soil areas in India. Such areas usually have clustered settlements. Related Concepts: • Clustered settlements are usually found in fertile plains and areas with favorable agricultural conditions. • Such settlements are characterized by houses being close to each other, forming a cluster. • Clustered settlements are common in regions with high agricultural productivity and dense populations.
