Verified by Experts

The correct Answer is:
A,B,C
(A)`AgCl` dissolves completely forming `[Ag(NH_(3))_(2)]Cl , AgCl+2NH_(4)OH to [Ag(NH_(3))_(2)]Cl+2H_(2)O`.
(B)`AgBr` dissolves completely forming `[Ag(NH_(3))_(2)]Br` soluble complex.
`AgBr+2NH_(4)OH to [Ag(NH_(3))_(2)]Br+2H_(2)O`
( C)`Ag_(2)CrO_(4)+4NH_(3) to 2[Ag(NH_(3))_(2)]^(+) +CrO_(4)^(2-)`
(D)`Agl` is insoluble in concentrated aqueous `NH_(3)`
