What statement best describes the economies of the north and south during civil war?

During the Civil War, the Northern economy was industrialized and diversified, benefiting from factories, railroads, and a larger workforce, which allowed it to sustain prolonged military efforts. In contrast, the Southern economy relied heavily on agriculture, particularly cotton, with a dependence on slave labor, making it less resilient and more vulnerable to blockades and resource shortages. This economic disparity significantly influenced the war's dynamics and outcomes.
