During field evaluation of a combine harvester, total grain collected at the grain tank was $135 \mathrm{~kg}$. Amount of threshed grain found over walker and shoe were $0.65 \mathrm{~kg}$ and $2.4 \mathrm{~kg}$, respectively. Unthreshed grain lost with straw and chaff were $4.54 \mathrm{~kg}$ and $0.28 \mathrm{~kg}$, respectively. Threshing efficiency of the combine harvester in percent is
(A) 94.37
(B) 94.49
(C) 96.50
(D) 96.63
