I'm not 100% sure, but I believe its because during that time the US was fighting Japan and many American citizens were fearful that Japanese Americans would turn against them in support of Japan. So for the safety of the Japanese Americans and for the overall comfort of the other citizens, the U.S. government at the time felt it was best to place them in internment camps. What the U.S. government didn't realize was that this caused more problems and cost more money in the future. I hope this helps.
The answer is B. attempted to restrict Japan's
growth and power. As it expanded its hold in Asia, the U.S. feared that
it would threaten their interests in the region. They tried setting up trade embargoes against
the Japanese but eventually this led to conflict that began with the bombing of
Pearl Harbor.
