What was the effect of the supreme court's decision referred to as "brown ii"?

The Supreme Court case of Brown vs Board II results in the Supreme Court demanding that all schools desegregate "with all deliberate speed."

During the first Brown v. Board case, the Supreme Court ruled that the "separate but equal" (established in Plessy vs. Ferguson) was illegal. The court argued that separate can never be equal and that this includes in America's public schools.

However, many all white schools refused to follow this law. This resulted in the Supreme Court having to establish that this needed to be done with "all deliberate speed." Since this terminology is vague, several white schools take several years to integrate schools. This results in more hostility between whites and African-Americans throughout the US.

The answer is option b and c.
