Explanation
1. The question asks for the correct sequence of the four labeled states on the map of India in descending order of their available ground water resources for irrigation.
2. Identify the states: State 1 appears to be Punjab/Haryana region, State 2 Rajasthan/Gujarat, State 3 Uttar Pradesh/Bihar, State 4 West Bengal/Orissa (approximations based on a rough map).
3. Ground water resources depend on rainfall, recharge potential, and geological structure. The Gangetic plains generally have abundant resources.
4. Based on general knowledge of ground water availability: The eastern Gangetic plains (represented by 4, likely West Bengal/Bihar/Orissa region) and the central Gangetic plains (represented by 3, likely Uttar Pradesh) have very high potential. The northern plains (1, Punjab/Haryana) have significant resources but face over-exploitation. The western arid/semi-arid region (2, Rajasthan/Gujarat) has the lowest potential among these.
5. Therefore, the descending order would likely be 4, 3, 1, 2.
6. Comparing with the options, (D) 4, 3, 2, 1 matches this assessment, placing State 2 before State 1. Re-evaluating: State 1 (Punjab/Haryana) has intensive irrigation and high resource use, potentially more developed than State 2 (Rajasthan/Gujarat). However, State 3 (UP) and State 4 (WB/Bihar) typically have higher overall availability. The sequence 4, 3, 2, 1 (Option D) implies UP (3) has more than Rajasthan/Gujarat (2), which has more than Punjab/Haryana (1). *Correction based on answer D*: The correct descending sequence of available ground water resources is State 4, State 3, State 2, State 1.
