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 ratio of metering disc to ground wheel for obtaining the desired plant population is
(A) 0.125: 1
(B) 0.150: 1
(C) 0.225: 1
(D) 0.250: 1
