Answer:
C
Step-by-step explanation:
The court's decision in the case increased inter-sectional tensions that ultimately sparked the Civil War by denying African Americans citizenship.
The Dred Scott case was a pivotal point in American history since it not only resulted in the denial of citizenship to African Americans but also widened the gap between the North and the South about the subject of slavery. This ruling, which practically said that those who had been held as slaves and their descendants had no legal rights, increased the tensions that eventually led to the Civil War.
