The correct answer is B) Chinese peasants were higher than merchants.
One difference between Chinese society and the other River Valley civilizations was that Chinese peasants were higher than merchants.
In ancient China, merchants were at the bottom of the social class. At the top of the social occupational pyramid were the illustrated people or scholars, followed by the peasants, then the artisans, and at the bottom, the merchants.
The River Valley civilizations were ancient civilizations that developed and prospered by settling next to important rivers, as was the case of Sumeria -the oldest civilization on earth- that settled in the middle of the Euphrates and Tigris Rivers. The ancient Egypt civilization that settled in next to the Nile River, or the Indus Valley Civilization that settled in next to the Indus River.
