Answer: B
Correct answer: a confining layer of much lower permeability
A confined aquifer is sealed above by a bed of much lower permeability, so the water within it is under pressure greater than atmospheric and there is no water table inside it. Puncturing the confining layer lets the water rise up the borehole to the piezometric surface, and where that surface stands above the ground the well flows without pumping.
