Answer:
The cremation of Jews in the concentration camps.
Explanation:
Elie Wiesel's "Hope, Despair, and Memory" is his Nobel Prize lecture where he recounts his personal experiences during the Holocaust. In his lecture, he tells what he had witnessed during the Nazi regime and how the things that he saw, the memories must serve as a reminder to humans to not repeat the horrendous acts.
In the given excerpt from the text, Wiesel talks of <em>"the survivors"</em> and the memories that they remember. Talking of the <em>"victims"</em>, he recounts the suffering of these people. And through his description, we can know that he is talking about the concentration camps and how people, irrespective of age and gender, are burned in the chambers.
Thus, the correct answer is the third option.
