What do you need help with? The instructions seem pretty clear
the correct answer is A; ad hominem argument.
The right answer for the question that is being asked and shown above is that: "B. It deemed the actions of the school authorities to be unreasonable and unconstitutional." In his summary of the majority opinion, Fortas say the district court responded is that it deemed the actions of the school authorities to be unreasonable and unconstitutional.
I believe the answer would be B, It is a strong summary because it is objective and accurately expresses the paragraph's central idea. The summary does, in fact, have the central idea of keeping the truth from the media, and it is objective because the summary is unbiased to the paragraph, and their summary appears to be not influenced by personal feelings or opinions in considering and representing facts. It sticks to the central idea of the paragraph, and it doesn't stray from the central idea.
