Assessment using multiple values

I am building an assessment form with 25 questions. For each question there will be 4 values. One will be marked with M (for most likely) and one with an L (least likely), the other two fields will be left.

I need to get it that if the one of the fields is marked with an M then that disppears from the choices across these four, likewise when L is selected.

I have looked at Survey and Quiz and cannot see a way to do this. Is it possible? if so, how?

Example
Q1: gentle | persuasive | humble | original
