The correct answer is C. The ruling in Plessy v. Ferguson upheld the legality of segregated public facilities.

Explanation:

Plessy v. Ferguson is a case decided by the United States Supreme Court in 1896, which is considered a landmark decision in the history of the court. The court had to decide whether a law of the state of Louisiana, which prescribed separate compartments for citizens of white and black skin in railway trains, was contrary to the constitution of the United States or not. It denied this with seven votes to one, stating that the provision of separate facilities for whites and blacks was permissible under certain conditions. This ruling effectively established the principle of "separate but equal" as the basis of racial segregation in the southern states.
