Answer:
The right answer is:
D. Brown v. Board of Education of Topeka.
Explanation:
While the US Supreme Court in its ruling in the case Plessy vs. Ferguson upheld the constitutionality of racial segregation laws for public facilities as long as the segregated facilities were of equal quality, another landmark decision in 1954 revoked that previous decision. In 1954, the Supreme Court unanimously ruled that the racial segregation of children in public schools was unconstitutional. Brown versus Board of Education was a cornerstone of the civil rights movement.
