Consider a mixture 'X' which is made by dissolving 0.4 mol of [Co(NH₃)₅SO₄]Br and 0.4 mol of [Co(NH₃)₅Br]SO₄ in water to make 4 L of solution. When 2 L of mixture 'X' is allowed to react with excess of AgNO₃, it forms precipitate 'Y'. The rest 2 L of mixture 'X' reacts with excess BaCl₂ to form precipitate 'Z'. Which of the following statements is CORRECT?

(C) 'Y' is BaSO₄ and 'Z' is AgBr.
