What did the Supreme Court mean when it declared during World War II that race was a "suspect classification"?

Question

a. Any person of a different race, and particularly Japanese Americans, should be deemed suspicious until they could prove innocence.
b. Any law using race as a basis should be suspected of being an unconstitutional classification, but the burden would be on the one challenging the law to prove it.
c. Any classification based on race would undergo suspect scrutiny during Supreme Court review, and the rule maker would have to prove it was used because of a compelling public interest.
d. Any local, state, or national law using racial criteria was presumed to be unconstitutional unless it could be shown to be both necessary and compelling.
