The correct statement($s$) regarding $P , Q , R$ and $S$ is(are)
$(A)$ Reaction of $P$ with $R$ in the presence of $KOH$ followed by acidification gives
$(B)$ Reaction of $R$ with $O _2$ in the presence of light gives phosgene gas
$(C)$ $Q$ reacts with aqueous $NaOH$ to produce $Cl _3 CCH _2 OH$ and $Cl _3 CCOONa$
$(D)$ $S$ on heating gives $P$
$Zn^{2 + }(aq.) + 2e⇔ Zn(s)$; $→$ $ -0.762$
$Cr^{3 + }(aq) + 3e ⇔ Cr(s)$; $→$ $-0.740$
$2H^ +(aq) + 2e⇔ {H_2}(g)$; $→$ $0.00$
$Fe^{3+}(aq) + e ⇔ Fe^{2+}(aq)$; $→$ $0.770$
