The correct answer is 2. Brown v. Board of Education reversed government-institutionalized segregation.

Explanation:

Brown v. Board of Education is a court decision of May 17, 1954, in the United States Supreme Court, which established a ban on separate black and white schools in the United States.

The ruling formally abolished racial segregation in the US educational system, but it would still take a while before real racial segregation had been abolished, especially at universities. At the same time, the verdict became very important for integration in elementary and college level, and paved the way for the black civil rights movement in the United States.

The verdict in the Supreme Court under Earl Warren's direction was unanimous (9-0). It referred to the rights in the Fourteenth Amendment to the US Constitution. The judgment repealed the laws and judgments of the states where they allowed racially segregated schools, and rescinded Plessy v. Ferguson from 1896.
