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 H2S in a dilute mineral acid medium. However, it gave a precipitate (R) with H2S in an ammoniacal medium. The precipitate R gave a coloured solution (S), when treated with H2O2 in an aqueous NaOH medium.

The coloured solution S contains

A
$$F{e_2}{(S{O_4})_3}$$
B
$$CuS{O_4}$$
C
$$ZnS{O_4}$$
D
$$N{a_2}Cr{O_4}$$
