A colourless crystalline salt, on being ...

A colourless crystalline salt, on being heated, gives a coloured gas with a pungent smell. On being passed through an `AgNO_(3)` solution, this gas forms a white precipitate insoluble in `HNO_(3)` but readily soluble in an `NH_(3)` solution. Which of the following reaction can lead to the above observation?

A

`MgCl_(2)+H_(2)O to Mg(OH)Cl+HCl`

B

`(NH_(4))_(2)CO_(3) to 2NH_(3)+CO_(2)+H_(2)O`

C

`ZnSO_(3) to ZnO+SO_(2)`

D

`NaNH_(4)HPO_(4) to NaPO_(3)+NH_(3)+H_(2)O`
