(B) To find the oxidation number of $Fe$ in $K_3[Fe(CN)_6]$,let the oxidation number of $Fe$ be $x$.The oxidation number of $K$ is $+1$ and the oxidation number of the $CN^-$ ligand is $-1$.The sum of the oxidation numbers of all atoms in a neutral complex is $0$.Therefore,$3(+1) + x + 6(-1) = 0$.$3 + x - 6 = 0$.$x - 3 = 0$.$x = +3$.Thus,the oxidation number of $Fe$ is $+3$.
