Soybean is to be planted with a precision planter that meters 54 seeds per revolution of the metering disc powered from a ground wheel of diameter $490 \mathrm{~mm}$. The desired plant population is 44800 per ha with a row to row spacing of $0.75 \mathrm{~m}$. The germination percentage is $84 .$ The planter is to be operated at $2.5 \mathrm{~km} \mathrm{~h}^{-1}$ with a $10 \%$ skid of ground wheel.The angular speed of ground wheel in rpm is

(A) 20.3

(B) 24.6

(C) 28.3

(D) 32.6
