    Alright what we look at is this Kw=(Ka)(Kb) if given Ka we solve for Kb like this Kw/Ka=Kb so considering we start initial with knowing the conjugate acid then it must initial be a base and bases have Kb dissociation values. So i think it is D.

    I feel like the answer choices were different, maybe I just read them wrong last time.
