Final answer:
Option (a, c), The factors that were divisive and led to the Civil War were the economic differences between the industrialized North and the slave-dependent South, and the political differences over states' rights versus federal power.
Step-by-step explanation:
The two factors that were divisive and led to the Civil War included: a) Economic differences between the North and South, notably the North's industrialization and the South's reliance on slavery, and c) Political differences over issues such as states' rights and the power of the federal government.
The North's economy was rapidly industrializing, which created an economic system that differed greatly from the South's plantation economy, which was heavily dependent on slave labor. This economic disparity was a major source of tension between the two regions.
Additionally, the political debate around states' rights and the federal government's role played a significant part in the conflict, as Southern states wished to maintain more autonomy, particularly in matters like slavery, while the North increasingly supported a strong federal government that could enforce laws across all states.
