  B. Plessy v. Ferguson

Explanation:

  Brown v. Board of Education was a landmark decision of the U.S. Supreme Court in which they ruled that American state laws that established racial segregation in public schools are unconstitutional.

  They considered that these laws violated the Equal Protection Clause of the Fourteenth Amendment. In this decision, the Court overruled partially the Plessy v. Ferguson decision, in which the Court ruled that racial segregation was not itself a violation of the Fourteenth Amendment under the statement "separate but equal."

  I hope this answer helps you.
