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 green precipitate (R) `H_(2)S` in an ammoniacal medium. The precipitate (R) gave a coloured solution (S), when treated with `H_(2)O_(2)` in an aqueous NaOH medium.
The precipitate P contains

A

`Pb^(2+)`

B

`Hg_(2)^(2+)`

C

`Ag^(o+)`

D

`Hg^(2+)`
