It depends on the hidden premises and the context, but I would argue Option B is correct. During war, fear, patriotism and national security trump civil liberties - as bad as that may be. (Muslim Americans suffered the same fate after 911)
It has to be number three. The American government was scared that the Japanese Americans would "betray" America.
During World War II, the U.S. government interned Japanese Americans, limiting their constitutional liberties under the pretext of national security. The Supreme Court upheld these actions in Korematsu v. United States, illustrating that civil liberties may be curtailed in wartime. Therefore, a valid conclusion from this experience is that constitutional liberties may be limited during wartime.
