Answer:
A. The part of an aquifer where surface water reaches the water table
Step-by-step explanation:
The aquifers are underground natural reservoirs of water, mostly freshwater, though there are also some with saline water. The aquifer both gets water from outer sources, and it also loses water, be it in a natural way, or because of the human activities. The recharging is the manner in which the aquifer gets its water replenished. The recharging area is the area where the surface water manages to reach the aquifer, thus providing it with fresh, new reserves of water.
