C. Concerns about national security and espionage

Explanation:

Japanese-Americans were already being discriminated against and during the Attack on Pearl Harbor, they had seemed to be a threat to national security. As it was shown that some Japanese living in Hawaii took pictures of the Pearl Harbor naval base days before the attack. FDR made the decision to keep Japanese Americans in a secured area where they can supervise them. The Camps were not as bad as nazi concentration camps but still had affected many of the Japanese-Americans living in them.
