The correct answer is C.

The Plessy v. Ferguson was a landmark case from the US Supreme Court, issued in 1896.

It confirmed that segregated facilities were not violating the US constitution as long as the ones for whites and the ones for black citizens were equal in quality. From this decision, the principle "separate but equal" was derived.

It actually gave legitimacy to the Jim Crow laws that many Southern States were enacting, and which promoted segregation and indirect discriminations.
