The correct answer is:
B) The Piedmont and Coastal Plains regions provided a combination of suitable soil and climate for cotton production.
The Piedmont Region and Coastal Plains regions were the cotton belt of the antebellum times. It was the rise of cotton what principally revitalized the institution of slavery in the south. By the end of the 18th century, in addition to proper soil and climate, technical improvements made cotton production more productive.
