Simple Explanation
Fertile plains agriculture के लिए attractive हो सकते हैं, लेकिन repeated severe floods settlement risk बढ़ा सकते हैं। लोग elevated land, embankment-protected areas या safer towns की ओर shift कर सकते हैं। इसलिए चौथा विकल्प सही है। Population distribution physical benefits और hazards दोनों के balance से बनता है। परीक्षा में fertile land को automatically dense population का guarantee न मानें; hazard exposure भी settlement pattern बदल सकता है। / Fertile plains may attract settlement because of agricultural advantages, but repeated severe floods can increase risk. People may shift toward elevated land, protected areas, or safer towns. Therefore, the fourth option is correct. Population distribution reflects a balance between physical benefits and hazards. In examinations, do not assume fertile land automatically guarantees dense settlement because hazard exposure can also reshape population patterns.
