Read the text below and answer the question that follows:
In May 2026, the Ministry of Jal Shakti released the updated National Aquifer Mapping and Management Programme (NAQUIM 2.0) guidelines for groundwater restoration. Under these guidelines, Grade-1 drought-prone districts are mandated to construct subsurface dykes only in non-alluvial riverbeds with a minimum slope of 3%. For coastal aquifers experiencing saltwater intrusion, the guidelines strictly prohibit deep tube-well extraction beyond 40 meters, while allowing shallow dug-wells up to 15 meters provided rainwater harvesting structures are installed within 500 meters of the extraction point. Funding assistance of 70% is extended exclusively to Gram Panchayats that achieve 100% metering of agricultural pumpsets, whereas urban municipal bodies receive a flat 50% subsidy regardless of pump metering.
Based on the passage provided above, which of the following conditions explicitly permits groundwater extraction using shallow dug-wells in coastal aquifers experiencing saltwater intrusion?
- Extraction is restricted to a depth of up to 15 meters, accompanied by a rainwater harvesting structure within 500 meters of the extraction point.Cevap
- BExtraction depth is maintained below 40 meters provided the local Gram Panchayat achieves 100% metering of agricultural pumpsets.
- CExtraction occurs in non-alluvial riverbeds having a minimum slope of 3% following approval of a 70% funding assistance grant.
- DExtraction is allowed up to 15 meters provided the urban municipal body receives a flat 50% subsidy for installation.
