Simple Explanation
Permanent ice-covered regions अत्यधिक cold conditions, limited agriculture और difficult accessibility के कारण बहुत कम population support करते हैं। इसलिए चौथा विकल्प सही है। Fertile deltas, industrial corridors और major ports generally settlement and economic activity के लिए अधिक favorable होते हैं। परीक्षा में permanently frozen and polar regions को sparse population के उदाहरण के रूप में याद रखें। / Permanently ice-covered regions support very small populations because of extreme cold, limited agriculture, and difficult accessibility. Therefore, the fourth option is correct. Fertile deltas, industrial corridors, and major ports are generally more favorable for settlement and economic activity. In examinations, remember permanently frozen and polar regions as examples of sparse population.
