Answer: D, blacks and whites were allowed to have separate voting facilities as long as they were provided equal representation in the state.
Explanation:
From history.com: "the Court ruled that the protections of 14th Amendment applied only to political and civil rights (like voting and jury service), not “social rights” (sitting in the railroad car of your choice)."
A is wrong because nobody was "allowed" to be segregated. It was more of a forced thing.
B is wrong because this didn't address women's rights.
C is wrong because they weren't allowed equal access to public facilities; they were segregated.
D is correct, since they ruled segregation was fine, as long as it didn't affect your political and civil rights.
