(B) In $C_6H_5CHO$ (benzaldehyde),the structure consists of a benzene ring attached to an aldehyde group $(-CHO)$.For the benzene ring $(C_6H_5-)$,the average oxidation state of each carbon is $-1/6$,so the sum for $6$ carbons is $-1$.The carbonyl carbon in the $-CHO$ group has an oxidation state of $+1$.Therefore,the sum of the oxidation numbers of all $7$ carbon atoms is $(-1) + (+1) = 0$.

The sum of the oxidation numbers of all the carbons in $C_6H_5CHO$ is
