D is correct for apex

D) While the Plessy decision established the doctrine of "separate but equal," the Brown decision stated that separate was always unequal.

Explanation:

Both Supreme Court cases dealt with the interpretation of the 14th amendment. More specifically, they both revolved around the interpretation of the Equal protection clause. This clause was supposed to ensure the equal treatment of all citizens within a state, regardless of race.

In 1896, the Supreme Court case Plessy vs. Ferguson ruled that "separate but equal" facilities for black and white citizens was not a violation of this amendment. However, the 1954 case in Brown vs. Board of Education ruled that "separate but equal" did violate the 14th amendment. The Brown vs. Board of Education case resulted in the desegregation of public schools.
