The outcome of the Supreme Court's Dred Scott case decided that Question 14 options: Slaves that lived on free soil after one year were free. slaves could sue for freedom in a federal court. Slaves were not citizens, but the property of their owner slaves could purchase freedom after gaining citizenship

The decision effectively stated that states could not be 'free' or a 'slave state' because its unconstitutional for states to exclude slave ownership in territories. The decision also stated that slaves were not citizens, thus could not sue in federal court. The best answer is that slaves were not citizens.
