b) By living in Missouri, Scott was no longer a slave,

The answer would be C.

Explanation:

In the Dred Scott v. Stanford Case, Chief Justice Taney ruled that all African Americans, whether free or a slave, were not American citizens and could never be American citizens, as well as they were just "property". He used the Declaration of Independence by quoting the phrase "all men are created equal..." is too broad and that African Americans were not part of this (which is not true). In addition, by stating this ruling, the Missouri Compromise of 1820 was declared unconstitutional allowing slavery in all country's and territories in the United States. Later on, as we see, Abolitionists such as Frederick Douglas, would see this court decision and fight against it, bringing even more attention to the issue of slavery.
