A tracer takes 100 days to travel from Well- 1 to Well- 2 which are $100 \mathrm{~m}$ apart. The elevation of water surface in Well- 2 is $3 \mathrm{~m}$ below that in Well-1. Assuming porosity equal to $15 \%$, the coefficient of permeability (expressed in $\mathrm{m} /$ day $)$ is

(A) 0.30

(B) 0.45

(C) 1.00

(D) 5.00
