Based on historical records, the Supreme Court case Korematsu v. the United States affected Executive Order 9066 as " It voted 6-3 to uphold the order, deeming it was a military necessity. "

Hence, in this case, it is concluded that the correct answer is option B. "It voted 6-3 to uphold the order, deeming it was a military necessity."
