A permeable rock layer bounded above and below by impermeable rocks and containing groundwater under pressure is called what?

Answer and explanation

Correct answer: आबद्ध जलभृत (Confined aquifer)

Correct answer: B, a confined aquifer. An aquifer is a permeable underground layer, such as porous sediment or fractured rock, that can store and transmit groundwater. In a confined aquifer, impermeable or very poorly permeable layers occur above and below it. Water entering the aquifer elsewhere becomes trapped under pressure because it cannot freely rise through the confining layers. If a well reaches this aquifer, the water level may rise above the top of the aquifer; in some situations it may even flow out, depending on the pressure. A is wrong because an unconfined aquifer has no impermeable upper confining layer and its water table is exposed to atmospheric pressure. C is wrong because a perched water table is a small, local accumulation above a limited impermeable lens, not necessarily a regionally confined pressured aquifer. D is wrong because an artesian well is the well or borehole that taps pressurised groundwater, not the rock layer itself. Memory cue: confined describes the aquifer; artesian describes a pressure-fed well.
