Match List I with List II :

List-I	List-II
(A)	(I) (i) oleum; (ii) \(H _2 O / H ^{+}\) (iii) \(H ^{+}\)
(B)	(II) (i) \(O _2\); (ii) \(H _2 O / H ^{+}\)
(C)	(III) (i) \(CH _3 OH , H ^{+}\); (ii) \(H _2\), catalyst
(D)	(IV) (i) conc. \(H _2 SO _4, \triangle\); (ii) \(H ^{+} / H _2 O\)

Choose the correct answer from the options given below:

(B) A-II, B-III, C-IV, D-I
Reaction A: Cumene (isopropylbenzene) is oxidized in the presence of air ( \(O _2\) ) to form cumene hydroperoxide, which upon subsequent treatment with dilute acid \(\left( H _2 O / H ^{+}\right)\)yields phenol and acetone. Thus, A matches II.
Reaction B: Acetic acid \(\left( CH _3 COOH \right)\) can be converted to ethanol by first reacting with methanol in the presence of an acid catalyst to form methyl acetate (esterification). The ester is then catalytically hydrogenated ( \(H _2\), catalyst) to yield ethanol and methanol. Thus, B matches III.
Reaction C: Propan-1-ol is dehydrated using concentrated \(H _2 SO _4\) and heat to form propene. Acid-catalyzed hydration ( \(H ^{+} / H _2 O\) ) of propene follows Markovnikov's rule to yield propan-2-ol. Thus, C matches IV.
Reaction D: Benzene is sulfonated using oleum to form benzenesulfonic acid. Heating with NaOH (fusion) converts it to sodium phenoxide, which on acidification \(\left( H ^{+}\right)\)gives phenol. Thus, D matches I.
The correct matching is A-II, B-III, C-IV, D-I.
