Some organic compounds possess fragrance and taste. Their names are given in Column-$I$,structures in Column-$II$,and their sources in Column-$III$. Match Column-$I$ with Column-$II$ and Column-$III$.

Column-$I$ (Name)	Column-$II$ (Structure)	Column-$III$ (Source)
$(A)$ Vanillin	$(i)$ $C_6H_4(OH)CHO$ (ortho)	$(p)$ From cinnamon
$(B)$ Salicylaldehyde	$(ii)$ $C_6H_5CH=CHCHO$	$(q)$ From seeds of vanilla
$(C)$ Cinnamaldehyde	$(iii)$ $C_6H_3(OH)(OCH_3)CHO$	$(r)$ From meadow sweet

(A) The correct matches are as follows:
$(A)$ Vanillin: Structure $(iii)$ ($4$-hydroxy$-3-$methoxybenzaldehyde),Source $(q)$ (From seeds of vanilla).
$(B)$ Salicylaldehyde: Structure $(i)$ ($2$-hydroxybenzaldehyde),Source $(r)$ (From meadow sweet).
$(C)$ Cinnamaldehyde: Structure $(ii)$ ($3$-phenylprop$-2-$enal),Source $(p)$ (From cinnamon).
Therefore,the correct matching is: $A$ $\rightarrow iii$ $\rightarrow q, B$ $\rightarrow i$ $\rightarrow r, C$ $\rightarrow ii$ $\rightarrow p$.
