Answer:
Option C, Dred Scott v. Sandford, is the right answer.
Step-by-step explanation:
The ruling in the Dred Scott v. Sandford case was a milestone judgement in the history of the Supreme Court of the United States. In this particular case, the U.S. Supreme Court held that the U.S. Constitution was not intended to give the citizenship of America to the Black community regardless of whether they were free or enslaved, and thus the rights associated with it and given to the citizens of America would not be applicable on them. Moreover, the Supreme Court declared that Congress does not have the power to eliminate slavery from any region of the United States.
