The answer would have to be option D "Justice." Media is used in different sort of ways. It will not be option A because entertainment is one of the main sources on why people use media to get the latest and entertain themselves on what is going on in that day. It will not be option B because school educators would use media that would help teacher his or her students on the lesson. It's not option C because advocacy is a public support which is mainly used in media campaigns.
Hope this helps!
