I say B.

Right.

You are correct, the U.S. Supreme Court case Brown v. Board of Education referred to racial segregation in American schools. The case was a landmark decision in 1954 that declared racial segregation in public schools to be unconstitutional. To arrive at this answer, one could start by understanding the four options provided and eliminating choices that are not relevant to the case. For example, options A, C, and D can be eliminated as they are not related to the topic of segregation in schools. This leaves option B as the correct answer.
