The correct answer is:

D. It marks the boundary between saturated and unsaturated soil.

The water table represents the upper surface of the zone of saturation, where all the pore spaces in the soil and rock are filled with water, distinguishing it from the zone of aeration above, where the pores contain both air and water.
