The correct answer is
(a) $P \rightarrow 1$; $Q \rightarrow 2,3 ; R \rightarrow 1,4 ; S \rightarrow 2,4$
(b) $P \rightarrow 1,5 ; Q \rightarrow 3,4 ; R \rightarrow 4,5 ; S \rightarrow 3$
(c) $P \rightarrow 1,5 ; Q \rightarrow 3,4 ; R \rightarrow 5 ; S \rightarrow 2,4$
(d) $P \rightarrow 1,5 ; Q \rightarrow 2,3 ; R \rightarrow 1,5 ; S \rightarrow 2,3$

The correct match is $1$ i.e., $I_2, NaOH$ and $5$ i.e., $NaOBr$ The reactions proceed as

The correct match is $2$ i.e. $\left[Ag\left(NH_3\right)_2\right]^+ OH^-$ and $3$ i.e., Fehling’s solution.
The reactions proceed as follows:

The correct match is $1,5$ again.
