An aqueous solution of a mixture of two ...

An aqueous solution of a mixture of two inorganic salts, when treated with dilute `HCl`, gave a precipitate `(P)` and a filtrate `(Q)`.The precipitate `P` was found to dissolve in hot water. The filtrate `(Q)` remained unchanged, when treated with `H_(2)S` in a dilute mineral acid medium. However, it gave a precipitate `(R)` with `H_(2)S` in an ammoniaca medium.The precipitate `R` gave a coloured solution `(S)`, when treated with `H_(2)O_(2)` in an aqueous `NaOH` medium.
The coloured solution `S` contains

A

`Fe_(2)(SO_(4))_(3)`

B

`CuSO_(4)`

C

`ZnSO_(4)`

D

`Na_(2)CrO_(4)`
