The correct option is C

The Fourteenth Amendment to the Constitution of the United States ('XIV Amendment') is one of the post-Civil War amendments, and includes, among others, the Due Process Clause and the Equal Protection Clause. It was proposed on June 13, 1866, and ratified on July 9, 1868. The amendment provides a broad definition of national citizenship, which annuls the decision of Dred Scott v. Sandford (1857), who had excluded slaves and their descendants, from possessing constitutional rights. It requires states to provide equal protection before the law to all persons (not just citizens) within their jurisdictions. The importance of the Fourteenth Amendment was exemplified when it was interpreted to prohibit racial segregation in public schools in the Brown v. Case. Board of Education.
