A metal complex having the molecular formula `Cr(NH_3)_4Cl_2`,Br have been isolated in two forms (A) and (B). The form (A) reacts with `AgNO_3` giving white precipitate readily soluble in dilute `NH_4OH` while (B) gives a yellow precipitate soluble in concentrated `NH_4OH`. Answer the following questions : The formula of complex A is

A

`[Cr(NH_3)_4Br]Cl_2`

B

`[Cr(NH_3)_4Cl Br]Cl`
