Answer: The correct answer is

Step-by-step explanation:
Ammonia is a base because it accepts
ions and Hydrochloric acid is an acid because it looses
ions.
So, the reaction between them, leads to the formation of a salt.
The equation for the reaction of ammonia and hydrochloric acid follows:

By Stoichiometry of the reaction:
1 mole of hydrochloric acid reacts with 1 mole of ammonia to produce 1 mole of ammonium chloride.
Hence, the salt formed is
