The correct statement about the reaction is:

NH3 is a base, and NH4+ is its conjugate acid.

In this reaction, ammonia (NH3) acts as a base by accepting a proton (H+) from water (H2O), which results in the formation of hydroxide ions (OH–) and ammonium ions (NH4+). Thus, NH4+ is the conjugate acid of NH3.
