B)The drawdown is the percentage of available water in the aquifer that has already been used.

Drawdown is the distance between the original water table and the water level in the well. The cone of depression is the cone-shaped depression in the water table around a pumping well caused by the removal of water from the aquifer. The drawdown and the cone of depression are related because as the water is pumped out of the well, the water level in the well drops, which causes the water table to drop in the surrounding area, creating the cone of depression.
