Answer:
B. A large professional middle class
Step-by-step explanation:
The antebellum South was primarily agrarian and had a more hierarchical social structure compared to the North. The planter elite, who owned large plantations and enslaved labor, held significant economic and social power, while there was a smaller middle class, which was not as large or professionally diverse as in the more industrialized North. The South's economy and society were primarily structured around agriculture and the plantation system.
