In the prepartion of `HBr` or `HI, NaX (X=Br,I)` is treated with `H_(3)PO_(4)` and not by concentrated `H_(2)SO_(4)` since,

A

`H_(2)SO_(4)` makes the reaction reversible

B

`H_(2)SO_(4)` oxidises `HX` to `X_(2)(Br_(2),I_(2))`

C

`Na_(2)SO_(4)` is water soluble and `Na_(3)PO_(4)` is water insoluble

D

`Na_(3)PO_(4)` is water insoluble and `Na_(2)SO_(4)` is water soluble
