The correct answer is C. Denied citizenship rights to blacks
Explanation:
Historically, Northerners opposed slavery, which was a common practice in the Southern states. In this context, northerners believed slavers should be freed and they should be given civil rights. Due to this, when Dred Scott, a black slave, tried to sue his master to obtain freedom as he had been in a "free" territory, and the Supreme Court determined rights from the Constitution did not protect black people (including the right to sue) most northerners were angry. This means the Dredd Scott decision angered northerners because it showed during that time black citizens did not have any rights and were not protected by the Constitution (option C).
