At a station, Storm I of 5 hour duration with intensity $2 \mathrm{~cm} / \mathrm{h}$ resulted in a runoff of $4 \mathrm{~cm}$ and Storm II of 8 hour duration resulted in a runoff of $8.4 \mathrm{~cm}$. Assume that the $\phi$ -index is the same for both the storms.The intensity of storm II (in $\mathrm{cm} / \mathrm{h}$ ) is:

(A) 2.00

(B) 1.75

(C) 1.50

(D) 2.25
