Answer
an appeal to credibility.
Why not the others: The sentence 'Think of the frightened child who waits alone in a dark hospital corridor.' is an appeal to emotion; 'Studies show that students who sleep eight hours score higher on exams.' is to logic (evidence); 'Everyone is talking about the issue' is a bandwagon appeal.
