Answer:
B) The Supreme Court ruled that under the constitution, African Americans are not citizens
Explanation:
The Fourteenth Amendment to the Constitution of the United States is one of the post-Civil War amendments, and includes, among others, the Due Process Clause and the Equal Protection Clause.
The amendment redefines national citizenship more broadly, nullifying the decision of Dred Scott v. Sandford (1857), who had excluded slaves and their descendants, from having constitutional rights. An example of the importance of the Fourteenth Amendment can be seen in Brown v. Board of Education, when it was interpreted to prohibit racial segregation in public schools.
