The answer that best analyzes the impact of the Supreme Court case rulings of Plessy v. Ferguson and Brown v. Board of Education on individual freedoms and equal protection is:
• Plessy v. Ferguson created the separate but equal doctrine and Brown v. Board ended the separate but equal doctrine in public education.
This option accurately reflects the historical significance of both cases: Plessy v. Ferguson upheld racial segregation under the "separate but equal" doctrine, which effectively legalized racial discrimination and reinforced Jim Crow laws. Brown v. Board of Education, on the other hand, decisively ruled that segregation in public education was unconstitutional, thereby dismantling the legal foundation for segregation established by Plessy.
