In upholding louisiana’s separate car act, the supreme court claimed that
a. segregation was not the same as discrimination.
b. the fourteenth amendment did not apply to southern states.
c. discrimination was necessary in order to maintain public order
d. segregation was unconstitutional based on the fourteenth amendment.

I believe the answer is: A. segregation was not the same as discrimination.

The Supreme Court claimed that segregation mean separated but equal.

But in the process, the discrimination of treatment between the racial majority and minority seem prevalent. For example, the school quality for white citizens were significantly better compared to the school for black citizens.

this question does't support enough resioning to answer.
