a.They both tried to end slavery in southern states.

Explanation:

What did the Missouri Compromise, the Compromise of 1850, and "Bleeding Kansas" have in common? The Missouri Compromise, the Compromise of 1850, and "Bleeding Kansas" all dealt with the expansion of slavery into the western territories. Each of them involved the balance of "free" and "slave" states in the Union.
