Which species in a NH4Cl/NH3 buffer reacts with acid?

I have a buffered solution containing 0.25M NH3 (Kb=1.8 × 103) and 0.40 M NH4Cl. If 1.0 mol of HCl, strong acid, is added to 1.0 L of the buffered solution, Which chemical species of the buffer would tend to react with the HCl?

If you're adding an acid (HCl), the additional hydrogen ions will react with the base in the buffer (NH3), producing more NH4+.
