C. Goods produced in one region could be sent to another and sold.
They had to defeat the Southern armies on the South's home soil.
They would have to occupy each seceding state.
The South faced much more hardship economically during the war (because their agricultural economy based on slave labor made mobilization of resources more difficult while the North's economic and industrial capacity soared during the war as it continued its rapid industrialization). In the South, the biggest problems were lack of labor, poverty and poor relief, especially in times of acute food shortages. Also, their money had no base and was ultimately worthless, making buying and selling goods extremely difficult. They couldn't get aid from foreign nations due to their lack of capital and resources to spare (and when cotton and other cash crop fields were destroyed and lost money, it was a nail in the coffin). The North, on the other hand, had a solid economy with money well-backed by gold and silver. Their industrialization also meant that the main problem faced, which they could recover from and work through, was labor shortages (from all men going to fight).
