Respuesta :
A, Slaves provided much of the labor on plantations that grew cash crops would be the answer I would go with. Most slaves worked in crop fields, and iron working didn't become prominent in the US until the industrial revolution about 10 years after the Civil War. I cannot say I'm 100% certain, but the others to me don't seem to make sense when looking at the situation.
Slaves provided much of the labour on plantations that grew cash crops, were slave labour so important to the economy of the Southern colonies. Hence, option A is correct.
What are cash crops?
Crops that are grown for either export or local market sales. In addition to meals like coffee, chocolate, sugar, vegetables, and peanuts, they also include non-foods like cotton and tobacco. Cash crops now occupy a sizable portion of the land in emerging countries.
The highest yielding crops are sugar cane, sugar beets, and tomatoes. In the world, sugar cane accounts for around 80% of sugar production, with sugar beet accounting for the remaining 20%. Unsurprisingly, many areas of the world forbid the highest earning cash crops in terms of value per acre.
Thus, option A is correct.
