Answer: b. God must be cruel or a figment of the imagination
Step-by-step explanation:
Elie Wiesel was a holocaust survivor that has spoken at length about the atrocities he witnessed in the concentration camps as the Nazis effected their "Final solution" to exterminate all Jews.
Mr. Wiesel saw things in the camp that were so cruel that he wondered why God would not stop them. To rationalize why God would not stop them, he came to a decision that God either did not exist or was cruel for allowing such things to happen.
Mr. Wiesel has since said that he still believes in God however and it is because of this belief that he was so angry that God did not save those who were killed in the holocaust.
