The correct option 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 $2$ i.e. $\left[Ag\left(NH _3\right) _2\right] OH$ and $3$ i.e., Fehling’s solution.

The reactions proceed as

The correct match is $2,3 $.

The reaction proceed as
