X → KOH Y (gas turns red litmus blue) + Z → Zn + KOH Y (gas) . X → Δ gas (does not support combustion) Identify (X) to (Z):

X = NH 4 NO 2 Y = NH 3 Z = KNO 2

X = ( NH 4 ) 2 Cr 2 O 7 Y = NH 3 Z = Cr 2 O 3

X = ( NH 4 ) 2 SO 4 Y = NH 3 Z = K 2 SO 4

X = NH 4 NO 3 Y = NH 3 Z = KNO 3

A white crystalline solid 'A' on boiling with caustic soda solution gives a gas 'B' which on passing through an alkaline solution of potassium tetraiodomercurate (II) solution gives a brown ppt. The substance 'A' on heating evolves a neutral gas 'C', which is inert at room temperature and reactive in the presence of catalyst and does not give brown fumes with nitric acid oxide.

The gas 'C' is

A compound (A) on heating with an excess of caustic soda solution liberates a gas (B) which gives white fumes on exposure of $HCl$ . The resultant alkaline solution thus obtained after heating again liberates the same gas (B) when heated with zinc powder. Compound (A) on heating alone gives a neutral oxide of nitrogen not nitrogen gas. Choose the correct statement from the following:
