खालीलपैकी कोणत्या घटकाचा मानवी वसाहतीवर परिणाम होतो ?
(a) भूपृष्ठरचना
(b) पाणी
(c) सूर्यप्रकाश

The correct answer is Option D ((a), (b) and (c)).

Key Points:
• Factors Determining Human Settlements:
• (a) Topography (Relief): Flat plains and river valleys support dense settlements, while rugged, steep mountains restrict habitation.
• (b) Water Supply: Water is vital for drinking, domestic use, agriculture, and industry; hence ancient and modern settlements are established as 'wet point' settlements near rivers, lakes, and springs.
• (c) Sunlight / Insolation (Aspect of Slope): Particularly in mid-to-high latitude and hilly regions, settlements are deliberately situated on sun-facing slopes (Adret slopes in the Alps/Himalayas) to ensure warmth, longer daylight, and agricultural viability.
• All three physical geographic factors—topography, water availability, and sunlight—directly influence the siting and morphology of human settlements (Option 4).
• Key Takeaway: Topography, water availability, and solar radiation exposure collectively determine the location and growth of human settlements.
