Explanation:

The question is a match-the-following based on identifying the correct reagent required to carry out specific organic transformations.

Concept:

This question is based on selective organic reductions and dehydrations of functional groups , especially:

Dehydration of amides

Reduction of esters, lactones, and acid chlorides

Controlled (partial) reduction to aldehydes

List - I	List - II
(A) $PhCONH_{2} ⟶ Ph - C \equiv N$ (C)	(P) $P_{2} O_{5}$
(B)	(Q) LiAlH₄
(C)	(R) $H_{2} / Pd - BaSO_{4}$
(D)) $CH_{3} COCl ⟶ CH_{3} - CHO$	(S) DIBALH
