Answer:
In the South during the Antebellum period, the years between the late 1700s and the first half of the 1800s, what most differentiated the elite and the poor was the land ownership (A).
Explanation:
The South during Antebellum was largely agricultural. Unlike northern states that were industrializing and creating many different jobs and specializations, the south focused its economic activities on agriculture.
Because of this land property was the main differentiation between classes, which means that this region was immensely unequal. Who had land formed the elite, and who hadn't was poor and had to work for the elite to survive.
