Explanation:

The Dred Scott case ruling addressed whether African Americans (enslaved and free) had basic citizenship rights. The other options: addressing moral right/wrong of slavery wasn't its focus, it didn't rule on slavery in South (it was already legal there) or outlawing in territories (the ruling actually upheld that Congress couldn't ban slavery in territories, but the key citizenship question was central).

Answer:

whether African Americans – both enslaved and free – had basic citizenship rights.
