C. People of different races could be restricted to separate areas in public places.
Explanation:
The 1857 Supreme Court case of Plessy vs. Ferguson held that separate but equal facilities are constitutional. This means that racial segregation is legally constitutional as long as it has equal facilities for both races.
This case was a result of an incident when Homer Adolph Plessy, a mixed-race man was traveling in a train bound for Louisiana. He sat at the whites-only section of the train for which he was asked to move to the blacks section which he refused. Convicted of breaking the law, Plessy filed a petition against Hon. John H. Ferguson, the judge who presided over the case. The court ruled in favor of the state with the conclusion that since the train had equal facilities for both races and convicted Plessy.
