(B) The structures of the given compounds are as follows:$I$. Cinnamaldehyde ($3$-phenylprop-$2$-enal): $C_6H_5-CH=CH-CHO$$II$. Salicylaldehyde ($2$-hydroxybenzaldehyde): $A$ benzene ring with a $-CHO$ group at position $1$ and a $-OH$ group at position $2$.$III$. Vanillin ($4$-hydroxy-$3$-methoxybenzaldehyde): $A$ benzene ring with a $-CHO$ group at position $1$,a $-OH$ group at position $4$,and a $-OCH_3$ group at position $3$.Comparing these with the given options,option $B$ correctly represents the structures of cinnamaldehyde,salicylaldehyde,and vanillin in that order.

column-$I$	column-$II$
$(i)$ $CH_3COCH_3$	$(a)$ Aldehyde,$(b)$ Ketone
$(ii)$ $CH_3CH_2CHO$	$(c)$ Propanone,$(d)$ Oxo
$(iii)$ $CH_3CH_2COOH$	$(e)$ One,$(f)$ al
	$(g)$ Propanoic acid

The structures of cinnamaldehyde $(I)$,salicylaldehyde $(II)$,and vanillin $(III)$ are:
