A valid conclusion based on the experience of Japanese Americans during World War II is that in wartime
1.first-generation immigrants become security risks 2.constitutional liberties may be limited 3.loyalty oaths are necessary to protect the national interests 4.fear and uncertainty do not interfere with normal life
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)
