Hi there
Result of brown vs board of education Supreme Court decision
On May 17, 1954, U.S. Supreme Court Justice Earl Warren delivered the unanimous ruling in the landmark civil rights case Brown v. Board of Education of Topeka, Kansas. State-sanctioned segregation of public schools was a violation of the 14th amendment and was therefore unconstitutional.
I'd go with B because none of the other ones make any sense.
Hm..history questions like this are my weak point but i would probably say the reserve requirement?
