Options:

  • (A) the rate of recharge is more than the rate of groundwater discharge.
  • (B) the rate of recharge is equal to the rate of groundwater discharge.
  • (C) the rate of recharge is less than the rate of groundwater discharge.
  • (D) the pumping rate is more than the safe yield of the aquifer.
