Solution

The correct option is A $(A) N H_{4} N O_{3}, (D) N_{2} O$
Colourless salt $N H_{4} N O_{3} + N a O H △ ⟶ g a s (N H_{3})$ giving white fumes with $H C l +$ alkaline solution $(C)$
$N a N O_{3} + N a O H + Z n ⟶ g a s (N H_{3}) (A) △ ⟶ g a s (N_{2} O) + l i q u i d (H_{2} O)      b o t h t r i a t o m i c$ .
So $(A), (B), (C), (D)$ and $(E)$ are:
$(A) : N H_{4} N O_{3} (B) : N H_{3} (C) : (N a N O_{3} + N a O H) (D) : N_{2} O (E) : H_{2} O$ respectively.

Hence option $A$ is correct.
