Answer:
A. wartime condition.
Step-by-step explanation:
The Korematsu v. the United States case of 1944 was a landmark decision taken by the Supreme Court justifying and supporting the military decision to 'intern' Japanese-American citizens. This executive order was a result of the attack of Pearl Harbor by Japanese forces, which led America to take any American citizen of Japanese descent to "voluntary internment".
When Executive Order number 34 came, Fred Korematsu, a citizen of Japanese-American descent refused to comply with the internment. He was arrested on charges of violation of military orders. But even though he brought the case to the court, the court upheld the federal decision as constitutional.
The argument by Justice Hugo L. Black was that ". . . under conditions of modern warfare, our shores are threatened by hostile forces, the power to protect must be commensurate with the threatened danger."
Thus, the correct answer is option A.
