The correct answer:
Brown v. Board of Education reversed the decision in Plessy v. Ferguson.
Brown v. Board of Education (May 17, 1954) was a decision of the U.S. Supreme Court known as being a landmark in the country. The final ruling was that American state laws establishing racial segregation in public schools are unconstitutional, even if the segregated schools are otherwise equal in quality.
