Simple Explanation
fertile soil settlement के लिए favorable factor है लेकिन population distribution कई factors के संयुक्त प्रभाव से तय होता है। यदि region में conflict, poor transport, disease risk या market isolation हो तो fertility का लाभ पूरी तरह उपयोग नहीं हो सकता। इसलिए विकल्प A सही है। परीक्षा में single-factor explanation से बचकर multicausal approach अपनाना चाहिए। / Fertile soil is a favourable settlement factor, but population distribution is determined by several interacting influences. If a region faces conflict, poor transport, disease risk or market isolation, the advantage of fertile land may not be fully realised. Therefore option A is correct. In examinations, avoid single-factor explanations and use a multicausal approach.
