Explanation:

The Southern Colonies had an economic structure based on large - scale plantation agriculture (like growing tobacco, rice, indigo) which relied heavily on slave labor. This economic setup led to deep social stratification. The planter class (wealthy landowners) held significant power and wealth, there was a large enslaved population with no rights, and a small group of poor white farmers/indentured servants. So the most appropriate word to fill in the blank is "stratification" as it describes the division of society into different social classes with distinct levels of wealth, power, and status that the economic structure of the Southern Colonies fostered.

Answer:
