Answer:
C. ruled that Congress had no power to limit slavery in the territories
Explanation:
In Dred Scott v. Sandford (argued 1856 -- decided 1857), the Supreme Court ruled that Americans of African descent, whether free or slave, were not American citizens and could not sue in federal court. The Court also ruled that Congress lacked power to ban slavery in the U.S. territories.
One reason the decision in Dred Scott v. Sanford (1857) was so controversial is that it ruled that Congress had no power to limit slavery in the territories.
The decision was aiming for no rights provided to Americans of African descent that may create outrage in the society. The decision made it clear that no white men could be sued or obliged to respect African Americans.
Thus, the court also eliminated the powers of Congress to take any step for resolving the slavery issue in the society in order to maintain the balance between free and slave territories.
