    C)  Surface water is not naturally self-replenishing.

    Correct Answer: B

    Solution :

    [b] The current population of the world is using water at an alarming rate, and nature cannot keep up.

In industrialized countries, urban sprawl is increasingly paving over land, forcing rainfall to flow to surface water, rather than seeping back into underground aquifers. This is why groundwater replenishment programs are very important to the survival of the Earth and all of its inhabitants.
