`C_(6)H_(5)-COOH overset((i) CH_(3)Li("excess"))underset((ii) H_(3)overset(OPLUS)O)to`
`CH_(3)-COOH overset(MnO//300^(@)C)to`
`CH_(3)-CH_(2)-overset(O)overset(||)C-Cl overset(H_(2)//Pd-BaSO_(4))to`
`H_(3)C-underset(CH_(3))underset(|)CH-COOH overset("SOCl"_(2))to (A) overset((CH_(3))_(2)CULI)to`

Solution :(A) `C_(6)H_(5)-COOH overset((i)CH_(3)Li("excess"))underset((ii)H_(3)overset(oplus)O)to C_(6)H_(5)COCH_(3)`
(B) `2CH_(3)-COOH overset(MnO//300^(@)C)to CH_(3)-overset(O)overset(||)C-CH_(3)+CO_(2)+H_(2)O`
( C ) `CH_(3)-CH_(2)-overset(O)overset(||)C-Cl overset(H_(2)//Pd-"BaSO"_(4))to CH_(3)CH_(2)CHO`
(D)`H_(3)C-underset(CH_(3))underset(|)CH-COOH overset("SOCl"_(2))to (A) overset((CH_(3))_(2)"CuLi")to H_(3)C-underset(CH_(3))underset(|)CH-overset(O)overset(||)C-CH_(3)`
Hence, (A) is the correct answer.
