Detailed Explanation:

Answer: Option 3 — Statement-I is correct but Statement-II is incorrect

This question tests understanding of India's groundwater usage patterns and the primary purposes of extraction. Statement-I correctly cites the UN World Water Development Report 2022 data, while Statement-II incorrectly attributes the high extraction primarily to drinking water and sanitation needs.

✅ Statement-I – Correct: According to the UN World Water Development Report 2022, India extracts approximately 251 km³ of groundwater annually from an estimated 20 million wells and tube wells, which indeed represents more than a quarter (about 25-26%) of the world's total groundwater withdrawal.

❌ Statement-II – Incorrect: While India does need to cater to approximately 18% of the world's population, the major reason for high groundwater extraction is not drinking water and sanitation. Approximately 89% of India's groundwater extraction is used for irrigation purposes, not for drinking water and sanitation. Agriculture is the primary driver of groundwater depletion in India.

📝 Short Notes: India's Groundwater Usage

• Total Annual Extraction: Approximately 251 km³, the highest in the world (>25% of global extraction)
• Sectoral Distribution: ~89% for irrigation, ~9% for domestic use, ~2% for industrial use
• Infrastructure: Over 20 million wells and tube wells across the country
• Critical Concern: Unsustainable extraction rates leading to groundwater depletion, particularly in northwestern and southern India
• Key States Affected: Punjab, Haryana, Rajasthan, Gujarat, Tamil Nadu, and Karnataka face severe groundwater stress
• Recharge Gap: Extraction rates significantly exceed natural recharge rates in many regions, especially in agricultural belts
