(B) The formal charge $(FC)$ of an atom in a molecule or ion is calculated using the formula: $FC = V - L - \frac{B}{2}$ Where: $V$ = Total number of valence electrons in the free atom. $L$ = Total number of non-bonding (lone pair) electrons. $B$ = Total number of bonding (shared) electrons. For the Carbon $(C)$ atom in the given structure of $SCN^-$ $(S \equiv C - N:)$: $V = 4$ (Carbon is in group $14$) $L = 0$ (Carbon has no lone pairs) $B = 8$ (Carbon forms $3$ bonds with $S$ and $1$ bond with $N$,total $4$ bonds = $8$ electrons) $FC = 4 - 0 - \frac{8}{2} = 4 - 4 = 0$. Thus,the formal charge on the $C$ atom is $0$.
