Hey there! I believe your answer is B - Justice. I think this because just looking at it, its obviously not D or C. We then are left with the choices of A - Dedicated, and B - Justice. B is the better answer here, because an abstract noun is a quality, a concept, an idea, or maybe even an event. Dedicating is not exactly a quality, nor is it a concept or idea, and it sure as likely is not an event. That leaves us stranded with B - Justice, which is obviously a concept/quality.
