Solution

The correct options are
A Metal A is aluminium
D (D) is ammonia gas which on reacting with HCl gives $N H_{4} C l$
$2 A l A + N_{2} △ - \to 2 A l N B A B l N + H_{2} O \to A l (O H)_{3} C ↓ + N H_{3} D$
$A l (O H)_{3} C N a O H - ---- \to (d i s s o l v e s) N a A l O_{2} + H_{2} O$
$N H_{3} D H C l - - \to N H_{4} C l w h i t e f u m e s$
