The correct answer is B. The Supreme Court decision of Plessy v. Ferguson upheld the principle of separate but equal.

Explanation:

The ruling in the case Plessy v. Ferguson was a legal decision in the jurisprudence of the Supreme Court of the United States made in 1896, in which it was decided to maintain the constitutionality of racial segregation even in public places under the doctrine of "Separate but equal".

The verdict of seven votes to one was announced, with the majority opinion drafted by Judge Henry Billings Brown and the dissident by John Marshall Harlan. David Josiah Brewer did not participate in the decision. "Separate but equal" remained in the American laws until its challenge in 1954 by the Supreme Court ruiling in Brown v. Board of Education.
