Answer:
The answer is option B "And then I explain to him how naive we were, that the world did know and remained silent."
Step-by-step explanation:
The speech “Hope, Despair, and Memory,” was delivered by Elie Wiesel who was a Romanian-American writer and Holocaust survivor. He was awarded the Nobel Peace Prize in 1986 for this speech in which he takes a stand against inequality and urges humanity to feel compassion for others.
The line in which Wiesel appeals to the reader's sense of ethics is option B because, in it, he suggests that even when the whole world knew what was happening during the Holocaust they remained silent.
