Quizplus · Accepted Answer

An artesian well is a type of well where the water is under pressure, which causes it to flow to the surface without the need for pumping. This pressure is typically caused by the water being confined between two impermeable layers, such as clay or rock, that create a sort of underground reservoir. When a well is drilled into this type of aquifer, the pressure can force the water up and out of the well and into an artesian spring or natural discharge point. Therefore, option A is the correct answer.
