Answer :
The correct option is B
The Dred Scott Case against Sandford (also known as The Dred Scott Case) was a court case, crucial in the history of the United States, resolved by the Supreme Court of that country in 1857, in which it was decided to deprive any inhabitant of African descent, whether they were slaves or not, the right to citizenship and the authority to ban slavery in federal territories of the country was removed from Congress. The decision was drafted by Chief Justice Roger B. Taney. The fury that caused this failure among the abolitionists was an important factor in the explosion of the Civil War.
