applied the doctrine of popular sovereignty to parts of the west.

continued the Missouri Compromise line

repealed the Missouri Compromise line.

Answer 1

The correct answer is:

Both the Compromise of 1850 and the Kansas-Nebraska Act allowed for the territories of Kansas and Nebraska to decide through popular sovereignty whether to allow slavery, effectively undermining the Missouri Compromise line.
