Answer: Option A

Explanation: Social stratification relates to the division of its population into classes by the society based on sociology-economic factors such as wealth, employment, ethnicity, schooling, profession, and social standing, or related (social and political) strength.

In complex country-based, phallocentric, or feudal societies, the categorization of citizens by social strata exists most obviously, the latter centered on sociology-economic relations between classes of nobles and classes of the peasant.
