Match the reaction in Column-$I$ with the product in Column-$II$.

Column-$I$ (Reaction)	Column-$II$ (Product)
$(A)$ Dinitration of $4$-methylphenol	$(i)$ $2$-nitro-$4$-methylphenol + $2$-nitro-$5$-methylphenol
$(B)$ Mononitration of phenyl ethanoate	$(ii)$ $2,4$-dinitro-$5$-methylphenol
$(C)$ Dinitration of $3$-methylphenol	$(iii)$ $4$-nitrophenyl ethanoate
$(D)$ Mononitration of $3$-methylphenol	$(iv)$ $2,6$-dinitro-$4$-methylphenol

(A-IV, B-III, C-II, D-I) Dinitration of $4$-methylphenol ($p$-cresol) leads to the formation of $2,6$-dinitro-$4$-methylphenol,which corresponds to $(iv)$.
$(B)$ Mononitration of phenyl ethanoate gives $4$-nitrophenyl ethanoate as the major product,which corresponds to $(iii)$.
$(C)$ Dinitration of $3$-methylphenol ($m$-cresol) leads to the formation of $2,4$-dinitro-$5$-methylphenol,which corresponds to $(ii)$.
$(D)$ Mononitration of $3$-methylphenol leads to a mixture of $2$-nitro-$4$-methylphenol and $2$-nitro-$5$-methylphenol,which corresponds to $(i)$.
Therefore,the correct matching is: $(A-iv, B-iii, C-ii, D-i)$.
