A regime channel carrying a discharge of $25 \mathrm{~m}^{3} \mathrm{~s}^{-1}$ is designed using Lacey's regime theory. The side slope of the channel is $1 / 2 \mathrm{H}: 1 \mathrm{~V},$ and Lacey's silt factor is unity. The bottom width and depth of flow in the channel, in $\mathrm{m}$, respectively are

(A) 20.26,1.38

(B) 20.26,1.56

(C) 23.75,1.56

(D) 32.78,1.56
