Which of these statements BEST explains why the decision made in the "Dred Scott" case nullified the Compromise of 1850 and "popular sovereignty"?(1 point)

Question

Only the Supreme Court could determine whether a state could allow slavery not the Legislative branch.

African-Americans could not be considered citizens therefore no state could allow them to vote.

Slaves were considered property and the federal government could not disallow slavery in any state.

A state has the right to secede if the federal government tried to abolish slavery there.

Answer 1

The statement that BEST explains why the decision made in the "Dred Scott" case nullified the Compromise of 1850 and "popular sovereignty" is:

Slaves were considered property and the federal government could not disallow slavery in any state.

This reflects the ruling in the Dred Scott case, which stated that because slaves were considered property, the federal government had no authority to prohibit slavery in the territories, thereby undermining the principles of popular sovereignty and nullifying the compromises related to slavery made in the 1850s.
