Answer

Brief Explanations:

Artesian wells have water in a confined aquifer under natural pressure. This pressure forces the water to rise to the surface without the need for a pump. Water heated by magma is related to geothermal sources, water in impermeable layers doesn't define artesian wells, and artesian wells don't require mechanical pumps for water to reach the surface.

Answer:

The water is under pressure naturally and no pump is needed.
