<u>Answer:</u> The correct answer is NH_3 is the base and NH_4Cl is the salt.

<u>Explanation:</u>

Neutralization reaction is defined as the reaction in which an acid reacts with a base to produce salt and water as products.

According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and a base is defined as a substance which accepts protons.

For the given chemical reaction:

NH_3+HCl\rightarrow NH_4Cl

Here, NH_3 is a base because it is accepting proton and HCl is an acid because it is loosing proton.

NH_4Cl is considered as a salt because it is formed by the combination of acid and base.

Hence, the correct answer is NH_3 is the base and NH_4Cl is the salt.
