Answer: B. Land subsidence (the ground actually sinking) and dried-up wells.

Answer: (B)
Simple Explanation: Groundwater is like a bank account. If you keep withdrawing money (water) without depositing any (rain/recharge), the account goes empty, and the ground above can even collapse because there is no water left to support it.
