The ruling in brown v. board of education did not immediately end segregation in public schools because
northern states refused to follow it.
the supreme court did not offer a new policy.
southern states closed all their public schools.
the supreme court could not agree on a new policy.

The correct option is: "the Supreme Court did not offer a new policy."

Case Brown v. Topeka Board of Education, 1954, is a landmark judicial ruling by the Supreme Court of the United States that stated that state laws that established separate schools for African-American and white students denied equal educational opportunities.

The ruling was delivered on May 17, 1954, unanimously (9-0) by the Warren Court; and established that "separate educational facilities are inherently unequal". With this, the Supreme Court reversed the existing precedents from Plessy against Ferguson in 1896. As a result of this ruling, racial segregation came to be considered as a violation of the Equal Protection Clause of the Fourteenth Amendment to the United States Constitution. . This ruling opened the way for racial integration and achieving civil rights for African Americans.
