The two main arguments the Supreme Court use to uphold the constitutionality of Korematsu’s internment were " Due to the war, there was not enough time to hold trials or hearings before sending people to internment camps" and "The military had a legitimate need to protect against espionage and sabotage", option A and B are correct regarding the question.
Korematsu's parents were sent to the japan because they were born in japan but the Korematsu did not leave the country even after the order because he was born in America and was a American citizen. He stayed in america during the war but this is not a crime as he was American citizen.
The courts were not having sufficient time for the proper trials in the situation of war and the military had legitimate reasons for sending suspected people to their country and not allowing any sabotage.
