What are X, Y and Z in above reactions ?

Question

X + KOH + O₂ → Y + H₂O

Y + H₂SO₄ + Z + K₂SO₄ + MnO₂ + H₂O

What are X, Y and Z in above reactions ?

(A) X = K₂ MnO_4 , Y = MnO₂ , Z = KMnO₄ 

(B) X = K₂MnO₄ , Y = MnO₄ , Z = KMnO₄

(C) X = MNO₂ , Y = K₂ Mn₄ , Z = KmnO₄

(D) X = MnO₂ , Y = KmnO₄  MNO₄ , Z =K₂ MnO₄

Answer 1

(C) X = MnO₂ , Y = K₂  MnO₄ , Z = KMnO₄
