The reactions of `Cl_2` gas with cold-dilute and hot-concentrated NaOH in water give sodium salts of two (different) oxoacids of chlorine, P and Q, respectively. The `Cl_2` gas reacts with `SO_2` gas, in the presence of charcoal, to give a product R. R reacts with white phosphorus to give a compound S. On hydrolysis, S gives an oxoacid of phosphorus, T. Answer the following (11-12) questions: R, S and T, respectively, are

A

`SO_2Cl_2, PCl_5` and `H_3PO_4`

B

`SO_2Cl_2, PCl_3` and `H_3PO_3`

C

`SOCl_2, PCl_3` and `H_3PO_2`

D

`SOCl_2, PCl_5` and `H_3PO_4`
