Choose the Correct Answer

Correct Answer : Option c

Explanation
Statement 1 is correct: The North Indian Plains (e.g., the Ganga Plains) and Coastal Plains (e.g., along the Konkan Coast) are densely populated due to fertile land, favorable climate, and better access to resources. In contrast, the interior regions of southern and central India have relatively lower population densities due to more rugged terrain and less favorable agricultural conditions.

Statement 2 is not correct: The interior districts of southern Indian states (e.g., Deccan Plateau) and the Himalayas typically have lower population densities because of more challenging terrain and less fertile land. In contrast, deltas (like the Sundarbans Delta) and Coastal Plains tend to have higher population densities due to better access to water, fertile soil, and transportation routes.

Statement 3 is correct: Northern states such as Uttar Pradesh, Bihar, and West Bengal have higher population densities than many peninsular states like Maharashtra and Andhra Pradesh. The fertile plains and historical urbanization in the north have contributed to these higher densities.
