10 mins is unique about obtaining water from an artesian well?

the water is heated by magma or hot rocks.
the water is found in an impermeable layer.
the water is under pressure naturally and no pump is needed.
a mechanical pump must be installed to bring water to the surface.

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

Explanation:

An artesian well is a way of bringing groundwater to the surface. It does not require a pump to bring the water to the surface, but rather relies on the pressure in the aquifer to force water to the surface. The aquifer is a geologic layer of porous rock such as sandstone. Water builds up in this area between impermeable rocks, like clay which causes pressure to build. When an artesian well is drilled, water will force its way through to the surface once the aquifer is punctured resulting in an upward flow of water.

It's C/ The water is under pressure naturally and no pump is needed/ On Egenuity

Explanation:

i think that the best answer would be c.

tell me if im wrong : )

a. by using fur or clothes to trap heat energy near the body
