Assertion (A): Ganga Plain is the most densely populated part of India. Reason (R): Ganga is the most harnessed river of India.
- ABoth A and R are true, and R is the correct explanation of A
- BBoth A and R are true, but R is not a correct explanation of ACorrect
- CA is true, but R is false
- DA is false, but R is true
Explanation
The correct option is B because while both statements are individually true, the reason given does not explain the assertion.
Assertion A is true because the Ganga Plain is indeed the most densely populated region of India due to its fertile alluvial soil, flat terrain, perennial water supply, and favorable climate for agriculture and urbanization.
Reason R is true because the Ganga river system is the most harnessed in India, featuring numerous dams, barrages, and extensive canal networks for irrigation and hydroelectric power.
However, the high population density is primarily a result of the plains fertile land and historical suitability for settlement, rather than just the extent to which the river has been harnessed. Therefore, R is not the direct geographical or logical explanation for A.
