The correct answer is Brown II.

The original Brown vs. Board of Education case stated that "separate but equal" facilities violated the 14th amendment of the US Constitution. However, in this ruling, there was no mention of how long it should take schools to desegregate. That is why Brown II took place, as this case ruled that the desegregation of public schools in the United States needed to happen "with all delibertate speed."
