This exercise matches oxidation reactions with the correct oxidizing agents. Alkenes undergo specific oxidations: cis-dihydroxylation (OsO₄ or cold, dilute KMnO₄ known as Bayer's reagent), oxidative cleavage (O₃ then H₂O, or hot KMnO₄), and epoxidation followed by acid hydrolysis (RCO₃H then H₃O⁺).

Final Answer: The correct matches are determined by identifying the product type: cis-diol (P or Q), aldehyde/ketone (R or T), or trans-diol (S).
