    This is a complete list of strong acid and bases it should help you to answer this question.

    Also it is pretty important to know them all by memory for general chemistry

    yeah I was like what D doesn't even have a hydroxide group

    @Vera_ewing NH2R is considered a strong base as well

    And this is a bronsted base

    Yes you need to believe in yourself, also I gave you a link with all the strong acids and bases

    But it asks for OH- I think KOH would be safest.

    well bronsted acids and bases

    You kind of have to know them by memory I mean Group 1 and 2 elements OH will definitely be strong bases.

    true! Also depends on your definition of a base as well
