Which of the following is most likely to be associated with a confined aquifer?

A) perched water table
B) lake
C) artesian well
D) unsaturated zone

Confined aquifers are typically associated with artesian wells. In these systems, water is trapped between layers of impermeable rock or clay, which can cause the water to be under pressure. When a well is drilled into such an aquifer, the internal pressure might be sufficient to force the water up the well without the need for pumping, characteristic of an artesian well.
