Consider the above reaction. The percentage yield of amide product is ...... . (Round off to the Nearest Integer). (Given : Atomic mass : $C : 12.0\, u , H : 1.0 \,u,N : 14.0\, u , O : 16.0\, u , Cl : 35.5\, u )$

$(i)$ Methylamine $(ii)$ Phosgene
$(iii)$Phosphine $(iv)$ Dimethylamine

the final product $(C)$ is
