Answer: C) Lincoln opposed the spread of slavery into territories where it did not already exist.
Explanation: Prohibition of slavery in the southern states was the fear that proliferated during Lincoln’s campaign for residence. Since 1859, during his speeches, Lincoln strongly denounced slavery and started a rising political career based on that. Being elected, the whole nation wondered if Lincoln would accept secession of southern states against his one principles, and the response came in 1861 when Confederated South Carolina soldiers opened fire against Federal troops in Charleston and immediately, Lincoln requested for arms, soldiers and supplies to the remaining Union States.
