Final answer:
The most serious constitutional question raised by the presence of internment camps in the United States during World War II was the violation of detainees' rights to due process as guaranteed by the Fifth Amendment of the U.S. Constitution.
Step-by-step explanation:
The most serious constitutional question raised by the presence of internment camps in the United States during World War II was that most detainees were U.S. citizens held without charges or the prospect of a speedy hearing. This violated their rights to due process as guaranteed by the Fifth Amendment of the U.S. Constitution. The government justified this action by claiming it was necessary for national security, but it was later acknowledged as a grave violation of civil liberties.
