A horizontal axis drag type wind mill with square blades and a horizontal axis lift type wind mill with airfoil section blades having same rotor size are installed at a height of $10 \mathrm{~m}$ above the ground. The average wind speed is $25 \mathrm{~km} \mathrm{~h}^{-1}$. The maximum power coefficient for drag type and lift type wind mills is 0.148 and $0.593,$ respectively. If the maximum power extracted by drag type wind mill is $5 \mathrm{~kW}$, the corresponding power extracted by lift type wind mill, in $\mathrm{kW}$ is
(A) 8.43
(B) 12.63
(C) 18.03
(D) 20.03
