The correct response is:
The ruling was found in favor of the plaintiff, ruling that separate but equal is unconstitutional.
In Brown v. Board of Education, the Supreme Court utilized the process of judicial review to examine the constitutionality of state-sponsored segregation in public schools. The Court ultimately found that segregating public schools based on race violated the Equal Protection Clause of the Fourteenth Amendment, effectively overturning the "separate but equal" doctrine established in Plessy v. Ferguson.
