(A) Benzene and methylbenzene (toluene) differ by one –CH₂– unit, so they are homologous compounds (R).

(B) CH₃CH₂CH₂COOH (butanoic acid) and CH₃CH₂OCOCH₃ (ethyl acetate) have the same molecular formula but different functional groups, hence functional isomers (Q).

(C) n-Butane and isobutane have the same molecular formula (C₄H₁₀) but different carbon skeletons, so they are chain isomers (P).

(D) 1,1-Dimethylcyclohexane and 1,2-dimethylcyclohexane differ only in the positions of methyl groups on the ring, therefore position isomers (S).

Hence, the correct matching is A–R, B–Q, C–P, D–S
