किस कारण national average population density किसी देश के internal settlement pattern को पूरी तरह नहीं दिखाती?

Correct Answer: C. क्योंकि average dense और sparse क्षेत्रों के differences को छिपा सकती है / Because an average can hide differences between dense and sparse areas. Explanation: National arithmetic density total population को total area से divide करके एक average देती है। यदि population कुछ cities or river valleys में highly concentrated हो और large areas sparsely populated हों तो same national average इन internal contrasts को नहीं दिखाती। इसलिए तीसरा विकल्प सही है। परीक्षा में density को useful summary measure मानें लेकिन इसे exact local distribution का substitute न समझें। / National arithmetic density divides total population by total area and produces an average. If population is highly concentrated in a few cities or river valleys while large areas are sparsely populated, the national average does not reveal these internal contrasts. Therefore, the third option is correct. In examinations, treat density as a useful summary measure but not as a substitute for exact local distribution.
