How did the Plessy v. Ferguson decision affect racial relations in the South?

a. it forced white and African Americans to sue the same public facilities
b. it allowed segregation to continue legally
c. it improved the qualify of African American facilities
d. it ordered that segregation should be ended in public schools

i'm confused between B and C
"in this decision, the Court held that segregation was legal as long as the separate facilities provided for blacks were equal to those provided to whites.." i think the answer might be B ...."african american schools and other facilities in the south were rarely if ever made equal"

It's definitely B.

You are correct that the Plessy v. Ferguson decision allowed segregation to continue legally, so option B is the correct answer. The decision established the "separate but equal" doctrine, meaning that racial segregation was constitutional as long as separate facilities were provided for different racial groups and these facilities were equal in quality. However, it is important to note that in reality, African American facilities were rarely, if ever, made equal to those provided for whites. This decision had a significant negative impact on racial relations in the South as it reinforced and legalized racial discrimination and segregation.
