Solution

The correct option is A $N H_{4} C l$
Ammonia is a weak base and it combines with HCl to form ammonium chloride. But moisture is necessary to bring out this reaction. So when exposed to air they combine to form dense fumes of ammonium chloride. The salts produced by the action of ammonia on acids are known as the ammonium salts and all contain the ammonium ion.
