The option that would best fit with Abraham Lincoln's position during the debates of 1858 is the Kansas-Nebraska Act.
Lincoln opposed the spread of slavery into the territories, which was a key component of the Kansas-Nebraska Act. This act allowed for the possibility of slavery to spread into areas where it had previously been restricted, and it led to considerable conflict and violence, known as "Bleeding Kansas." Lincoln used the debates and his political activities to argue against the expansion of slavery, which aligns closely with his views regarding the Kansas-Nebraska Act.
