This question seems to be incomplete. However, there is enough information to find the right answer.
Answer: "The instincts of self-preservation, of self-defense, of pride, had all deserted us."
Explanation:
In "Night" (1960) Elie Wiesel describes his experiences in Auschwitz during the Holocaust. While the other options provide information related to what he experienced in camp, the first one best expresses the effect the camp had on the author. The idea that self-preservation had deserted all of them refers to the subjugation he and all the other prisioners experienced in the concentration camp.
