In early civilizations, the typical social class hierarchy often placed rulers and priests at the top, followed by merchants and artisans, with farmers and peasants at the bottom. Based on this understanding, the correct ranking from most to least valuable would be:
Rulers, priests, merchants, artisans, farmers, and peasants.
So among the options provided, none seem to match this exact order. However, the closest one that reflects a similar ranking would be:
Rulers and priests, merchants, artisans, farmers, and peasants.
If this ranking is not present among your choices, please verify if any of the listed options might represent this structure.
