A black powder (x) when heated with NaCl and Conc. H₂SO₄ liberates a greenish yellow gas (y). (y) on passing through liquor Ammonia liberates chemically inert gas (Z); and on passing through boiling KOH gives (A) and (B) along with H₂O₂ (A) When heated with (x) liberates another gas (C) and KCl. Then gases liberated are

A. y = Cl₂; Z = N₂; C = O₂

B. y = Cl₂; C = N₂; C = O₂

C. y = O₂; C = Cl₂; Z = O₂

D. y = Cl₂; C = NH₃; Z = O₂
