Answer:
A. Slaves were reserved for working only the largest plantations.
Step-by-step explanation:
Since the 1700s, South Carolina thrived on rice cultivation. During the mid-1730s, cotton was also grown in large quantities being exported to other countries. Selling cotton at competitive prices required a large amount of cheap labor. Thus thousands of people were forcibly brought from the African continent to work as slaves. With the expansion of cultivated area from the coast to the interior, more and more settlers and slaves settled in the region.
