Simple Explanation
population density प्रति unit area लोगों की average संख्या बताता है लेकिन वास्तविक resource pressure केवल population concentration से निर्धारित नहीं होता। water availability soil quality technology infrastructure consumption level और internal settlement pattern भी महत्त्वपूर्ण हैं। इसलिए विकल्प A सही है। high density वाला technologically efficient region resource stress manage कर सकता है जबकि low density वाला arid region severe scarcity झेल सकता है। परीक्षा में density को indicator मानें न कि पूर्ण measure। / Population density gives the average number of people per unit area, but actual resource pressure is not determined by concentration alone. Water availability, soil quality, technology, infrastructure, consumption levels and internal settlement patterns also matter. Therefore option A is correct. A high-density technologically efficient region may manage resource stress, while a low-density arid region may still face severe scarcity. Density should be treated as an indicator rather than a complete measure.
