7. This is an application of Bronsted-Lowry Theory of acids and bases.
Bronsted acid-bases only differ by a proton (H+).
i) If an acid loses its proton, it becomes conjugate base.
ii) If a base accepts a proton, it becomes conjugate acid.
Coming to the problem,
We know that NH3 is a base, and HCl is an acid.
So by rule (i), Cl- is the conjugate base.
By rule (ii), NH4+ is the conjugate acid.
So only the combination in option (e) is correct. HCl (acid), Cl- (conjugate base).
So option (e) is the correct option.
Hope this helps, thanks!
