Best ResponseYou've already chosen the best response.0there doesnt seem to be more than one group of options involved and it appears to be selection without repetition... I am guessing since its been awhile, but permutation. Would you happen to know the definitions of the words involved?

Best ResponseYou've already chosen the best response.0permutation is is when the order that is picked matters. Combination tends to refer to without order. So this I think is actually leaning towards combination
