Final answer:
The Dred Scott case involved a jury ruling Dred Scott legally free and Chief Justice Roger Taney declaring slaves as property.
Step-by-step explanation:
The correct statement is: A jury of white men in a Missouri court originally ruled Dred Scott legally free. In the Dred Scott case, Dred Scott, an enslaved African American, sued for his freedom in 1857. The Supreme Court, led by Chief Justice Roger Taney, ruled that Scott was not entitled to his freedom and that slaves were property, not citizens.
Taney also ruled that the Missouri Compromise, which prohibited slavery in certain territories, was unconstitutional. This decision further entrenched the institution of slavery and heightened tensions between the North and the South.
