Answer:
Correct order is: B. Nobles –Peasants –Artisans –Merchants
Explanation:
In the Confucian society hierarchy was not strictly followed, but they believed that their is difference between upper class, consisted out of nobles and peasant and lower class, consisted out of artisans and merchants.
This is as we can see much different than most of Ancient Civilization, where peasants usually were not that high on the hierarchy.
All other options are therefore wrong.
