Question

how is the founding principle popular sovereignty related to the dred scott v. sanford case?
the cases ruling upheld the principle because it gave formerly enslaved persons the right to vote in all elections.
the cases ruling hindered the principle because it stated that enslaved persons were property, even in free states.
the cases ruling upheld the principle because it restricted enslavers from bringing enslaved persons into free states.
the cases ruling hindered the principle because it stated that voters cannot prevent enslavement of people in their state.

Explanation:

Popular sovereignty is the principle that the people of a territory/state should decide key issues (like slavery) through their votes. In Dred Scott v. Sanford, the Supreme Court ruled that Congress and state voters could not ban slavery in U.S. territories, directly undermining popular sovereignty by stripping voters of the power to prevent slavery in their state/territory. The other options are incorrect: the ruling did not uphold popular sovereignty, did not give formerly enslaved people voting rights, and did not restrict enslavers from bringing enslaved people to free states.

Answer:

D. The case's ruling hindered the principle because it stated that voters cannot prevent enslavement of people in their state.
