Solution

The correct option is C $[P t {({N H}_{3})}_{4} {C l}_{2}] {B r}_{2}$ and $[P t {({N H}_{3})}_{4} {B r}_{2}] {C l}_{2}$
The complex having $B r$ and $C l$ out of coordination sphere only gives $A g B r$ (pale yellow ) and $A g C l$ (white ppt.) respectively upon reaction with $A g N O_{3}$ .
