Answer: The correct answer is: African Americans presented arguments in court that won them the right to attend previously segregated schools.
Explanation: In the Brown v. Board of Education case, African American parents and community members challenged the legality of the "separate but equal" doctrine, which allowed for racial segregation in public schools. They argued that segregation was inherently unequal and violated the 14th Amendment's guarantee of equal protection under the law. The case ultimately made its way to the Supreme Court, which ruled in 1954 that segregated schools were unconstitutional and violated the 14th Amendment. This landmark decision paved the way for the desegregation of schools across the United States.
