How does Wolff build an argument to persuade his audience that we should stop glorifying war (consider narrative genre characteristics and stylistic elements like concrete detail)

Hello. You have not shown which text this question refers to, which makes it difficult to answer it accurately and satisfactorily. However, I will try to help you in the best possible way.

To persuade the end of the glorification of war, an author of a speech, must show all the decadence it causes. The author must emphasize how war destroys, kills and causes fear, misery, despair and sadness. Nothing happy can be generated in a war, because even victory is achieved through death and destruction.

answer: the correct answer is b. an essay that connects the writer's experience with a topic of significance and of reader interest.

explanation: the key words are here "personal experience" since personal essays give insights about peoples' experiences in life and introduce us in their unique world that can be or not to related to our lives but interests us because we are human beings and share the same condition universally.  

appeal to ethos is your answer.
