Solution
The correct option is
D
an acid
In the reaction, water donates a proton to form hydroxide ion.
Thus, water is an acid and hydroxide ion is the conjugate base.
Ammonia accepts a proton to form ammonium ion.
Thus, ammonia is a base and ammonium ion is its conjugate acid.
Option A is correct.
