Reaction of iso-propylbenzene with $\mathrm{O}_{2}$ followed by the treatment with $\mathrm{H}_{3}\mathrm{O}^{+}$ forms phenol and a by-product P. Reaction of P with 3 equivalents of $\mathrm{Cl}_{2}$ gives compound Q. Treatment of Q with $\mathrm{Ca}(\mathrm{OH})_{2}$ produces compound R and calcium salt S. 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 (see structure); (B) Reaction of R with $\mathrm{O}_{2}$ in the presence of light gives phosgene gas; (D) S on heating gives P

(C) Q reacts with aqueous NaOH to produce $\mathrm{Cl}_{3}\mathrm{CCH}_{2}\mathrm{OH}$ and $\mathrm{Cl}_{3}\mathrm{CCOONa}$
