The correct answer is D) he argues that school is not for free speech.
One way in which Black argues against the majority opinion is that "he argues that school is not for free speech."
We are talking about the case Tinker v. Des Moines, in 1969, which changed the way students express freedom of speech in public schools. The court decision rued 7-2 in favor that the First Amendment applied to public schools and that the officials of the schools did not have the right to prohibit freedom of expression if they did not disrupt the educative process. However, Justice Hugo Black had a dissenting opinion saying that the students using armbands distracted the teacher's work and public schools were not a place for freedom of speech.
