Solution

The correct option is B $C a O + {2 N H}_{4} C l \to {C a C l}_{2} + H_{2} O + {2 N H}_{3}$
Ammonia gas $(N H_{3})$ can be prepared in the laboratory by heating calcium oxide and ammonium chloride. The ammonia gas formed is dried over $C a O$ .
The balanced reaction for above preparation is:
$C a O + {2 N H}_{4} C l \to {C a C l}_{2} + H_{2} O + {2 N H}_{3}$
