For a well to be a flowing artesian well, it must be:

Question

A. A confined aquifer with the pressure surface above the ground B. An unconfined aquifer with the pressure surface above the ground C. A confined aquifer with the pressure surface below the ground D. A confined aquiclude with the pressure surface above the ground E. An unconfined aquifer with the pressure surface below the ground

Answer 1

For a well to be classified as a flowing artesian well, it must be:

A. A confined aquifer with the pressure surface above the ground.

In a flowing artesian well, water in a confined aquifer is under pressure, and when a well is drilled into it, the pressure causes the water to flow naturally to the surface without the need for pumping, provided the pressure surface (the potentiometric surface) is above the ground level.
