Answer:
D. caste system
Explanation:
In india, the caste system is the social stratification that separate people based on their occupation. People with a certain type of occupation are considered to have higher social status compared to the other.
In general, the Caste system was divided into:
- Brahmin (priests/Academics)
- Ksahtrya (Warriors / Rulers)
- Vaishya (merchants / Landowners)
- Sudra (commoners, servants, /peasants)
This system might not exclusively enforced in modern India, but some characteristics of it might still be applicable to determine a person's social status. If you want to "move up" from the lower caste status, it can be done by changing one means of living and increasing your economic power.
