A translucent white waxy solid 'A' reacts with excess of chlorine to give a yellowish white powder 'B'. 'B' reacts with organic compounds containing $-\mathrm{O}\mathrm{H}$ group converting them into chloro derivatives. 'B' on hydrolysis gives 'C' and is finally converted to phosphoric acid. 'A', 'B' and 'C' are
