Solution

The correct option is D all
$[C o (S O_{4} (N H_{3})_{5})] B r \to [C o (S O_{4} (N H_{3})_{5})]^{+} + B r^{-}$ - gives test of bromide and $[C o B r (N H_{3})_{5}] S O_{4} \to [C o B r (N H_{3})_{5}]^{+ 2} + S O_{4}^{- 2}$ - gives test of sulphate. Both complexes give different ions in solution with different charge so they can be distinguished by all these methods.
