The statement that most directly relates to the creation of social stratification in early Asian agricultural settlements is:
Growing complexity in the social organization necessary for the group.
As agricultural settlements developed, they often led to increased food production, which, in turn, allowed for larger populations. This growth necessitated a more complex social organization, leading to different roles within the community, specialization of labor, and ultimately, the establishment of social hierarchies and stratification based on factors such as occupation, wealth, and power.
