A watershed of $100 \mathrm{~km}^{2}$ is underlain by an unconfined aquifer having hydraulic conductivity of $15 \mathrm{~m}$ day $^{-1}$ and specific yield of 0.20 . If 30 million $\mathrm{m}^{3}$ of water is pumped from this aquifer through uniformly distributed wells, the average drop of water table over the watershed in meter will be

(A) 1.50

(B) 0.75

(C) 0.06

(D) 6.00
