During the civil war, the south’s use of enslaved labor gave it an almost unlimited supply of soldiers more workers for its factories. a way to keep plantations running. a way to disrupt northern industry.

Ever seen Gone with the Wind? Almost at the beginning Rhett (Clark Gable who was the only one of the major characters not winning the Academy Award that should have) made the remark that the south will lose the war: they cannot make one cannon. He was immediately reviled by every other man in the room. B is definitely wrong.

The "Supply of Unlimited Soldiers" was to the North's advantage. The north promised freedom. The southern slaves liked the sound of that and they did obtain their freedom. Unfortunately, at the beginning, it did them little good. A is incorrect.

The former slaves and the slaves would never have thought of disrupting northern industry. They would gladly have worked there had there been decent wages paid. There weren't as it turned out. D is wrong.

The answer is C

your answer would be just capitalism.
