    The correct statement is C

    NH4 + is the conjugate acid of NH3

    Explanation:

    NH₃ + H₂O ⇌ OH⁻ + NH₄⁺

    Ammonia is the base

    Water is the acid

    So the conjugate pairs are.

    the acid, amonium

    the base, the hydroxide

    Water is also known as an amphoterus compound. It can act as an acid, or as a base at the same time. (Bronsted-Lory)
