NH3 because the rate of ionization in pure water is less than that of the others.

here is the hint: anything that goes with OH is a strong base. Of course, there are strong bases that doesn't have OH but generally, strong base contains OH. In this case NaOH and KOH are not weak bases.

a) NH3, because NH3 + H2O ===> "NH4OH," which is only partly ionized to NH4+ + OH-
NaOH and KOH are strong bases, because they are completely ionized. HCN is a weak acid, because only partly ionized to H+ + CN-.

im pretty sure A is. c and d are both strong acids because of the OH- and b just isnt a weak base.
