The answer is A- National Association for the Advancement of Colored People

Explanation:

The National Association for the Advancement of Colored People (NAACP) commenced in 1909.  In 1954, under the Special counsel of Thurgood Marshall and a team of NAACP attorneys, the NAACP won Brown v. Board of Education of Topeka, Kansas which was one one of their greatest legal victories. The Board v. Board of Education was a landmark decision of the U.S. Supreme Court in which the Court ruled that American state laws establishing racial segregation in public schools are unconstitutional, even if the segregated schools are otherwise equal in quality.

Brown consisted of six separate cases in five jurisdiction; Kansas, South Carolina, Virginia, the District of Columbia and Delaware. The cases are remembered as Brown because Oliver Brown was one of the several Plaintiffs in the Kansas case whose name appeared first in the court fillings.
