The correct answer is A) the plantation system.
The South economy relied on the plantation system before the civil war.
The plantation system was the basis of the economy in the Southern states. That is why slavery was so important for them. Slaves worked in the plantations farming the land of the owners. The plantation system was developed in Virginia and then spread all over the Southern states. The salves that worked in the plantation were not seen as humans but as property and that was cruel. Most of the plantations in the South harvested cotton that was exported. Cotton was the king in the South.
