Question

the court case plessy v ferguson challenged the legality of
racially segregated facilities.
scare tactics to enforce jim crow laws.
racially segregated housing.
\separate but equal\ schools.

Explanation:

Plessy v. Ferguson was a landmark U.S. Supreme Court case in 1896. The case centered around Homer Plessy, a man of mixed race, who challenged the constitutionality of a Louisiana law requiring racial segregation in public transportation (a type of racially segregated facility). The Court ruled in favor of the "separate but equal" doctrine, but the case specifically challenged the legality of racially segregated facilities. The other options: scare tactics to enforce Jim Crow laws were not the focus of this case; racially segregated housing was more related to other cases/contexts; "separate but equal" schools were challenged in Brown v. Board of Education, not Plessy v. Ferguson.

Answer:

A. racially segregated facilities.
