The reactions of Cl gas with cold-dilute and hot -concentrated NaOH in water give sodium salts of two (different)  oxoacids of chlorine, P and Q, respectively. The Cl2 gas reacts with SO2 gas , in the presence of charcoal, to give a product R. R reacts with  white phosphorous to give a  compound s, on hydrolysis, s gives an oxoacid of phosphorous T

R, S and T respectively, are

A) $SO_{2}Cl_{2}, PCl_{5}$ and $H_{3}PO_{4}$

B) $SO_{2}Cl_{2}, PCl_{5}$ and $H_{3}PO_{3}$

C) $SO_{}Cl_{2}, PCl_{3}$and $H_{3}PO_{2}$

D) $SO_{}Cl_{2}, PCl_{5}$and $H_{3}PO_{4}$
