Answer :
A is the corect answer he was none as chief justice Earl Warren.
The correct answer is A. In the Brown v. Board of Education case, as Chief Justice, Earl Warren convinced the other justices to issue a unanimous decision for the sake of national unity.
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 v. 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 14th Amendment to the United States Constitution. This ruling opened the way for racial integration and achieving civil rights for African Americans.
