The ruling in the dred scott case was so significant because it
(multiple choice)
a. whether or not slavery was morally right or wrong
b. whether african americans, both enslaved and free, had basic citizenship rights
c. whether slavery should be allowed in the south
d. whether territories could outlaw slavery

I'd say B. because the ruling didn't come out in his favor and it showed that African Americans had no basic rights.

B. Whether African Americans, both enslaved and free, had basic citizenship rights

Explanation:

Dred Scott was a slave in the state of Missouri, he moved to other states at the same time slavery was forbidden by the Missouri Compromise of 1820. With that, he filed a suit in the Missouri court asking for his freedom since he resided in a free territory.

The US Supreme Court decided that African Americans free or slaves were not considered American citizens and could not file lawsuits in a federal court and his case was dismissed.
