The correct answer is (a) Andhra Pradesh.
Andhra Pradesh has the highest replenishable groundwater resource in India, with an estimated 100 billion cubic meters of groundwater. This is more than double the amount of groundwater in the next highest state, Madhya Pradesh.
The groundwater in Andhra Pradesh is relatively clean and unpolluted, making it a valuable resource for drinking, irrigation, and industrial use. The state government has taken steps to protect the groundwater resource, including by regulating groundwater extraction and promoting rainwater harvesting.
The other options are incorrect. Madhya Pradesh has the second highest replenishable groundwater resource in India, with an estimated 45 billion cubic meters of groundwater. Uttar Pradesh has the third highest replenishable groundwater resource, with an estimated 35 billion cubic meters of groundwater. West Bengal has the fourth highest replenishable groundwater resource, with an estimated 25 billion cubic meters of groundwater.
Groundwater is a valuable resource that is essential for human life and economic development. It is important to protect groundwater resources from pollution and overuse.
