4) The case of Dred Scott v. Sandford (1856) is often called the Supreme Court’s great ‘self inflicted wound’ because the decision A) refused to give women the right to vote. B) created the doctrine of ‘separate but equal’. C) supported the South’s right to secede from the Union. D) ruled slaves to be property and incapable of becoming citizens.
The answer is D because Dred Scott was an escaped slave who didn't have any rights, even though he wasn't a slave anymore. He took his case to court and lost.
