(A-V, B-IV, C-II, D-I, E-VI) The matching is as follows:
$(A)$ Cyclohexanol corresponds to $(v)$ Cyclohexanol.
$(B)$ $2$-methylcyclopentanol corresponds to (iv) $2$-methylcyclopentanol.
$(C)$ $3$-methylphenol corresponds to (ii) $3$-methylphenol.
$(D)$ $1$-ethoxy-$2,2$-dimethylcyclohexane corresponds to $(i)$ $2$-ethoxy-$1,1$-dimethylcyclohexane (Note: Numbering starts from the ethoxy group as $1$ in the $IUPAC$ name).
$(E)$ Benzene-$1,2,4$-triol corresponds to (vi) Benzene-$1,2,4$-triol.
Therefore,the correct matching is: $(A$ $\rightarrow v), (B$ $\rightarrow iv), (C$ $\rightarrow ii), (D$ $\rightarrow i), (E$ $\rightarrow vi)$.
