Answer :
The Zhou were good rulers and kept by the will of the gods. Religion and association to god or divine power was used to justify power.
The correct answer is A) The Zhou were good rulers and kept power by the will of the gods.
The Zhou dynasty lasted for 800 years. This might indicate to an ancient Chinese person who believes in the Mandate to Heaven that the Zhou were good rulers and kept power by the will of the gods.
Historians consider that the Zhou Dynasty was the longest-lasting in the history of ancient China. It started in 1046 and ended in 256 BCE. This dynasty had wise men that produced a prolific period in arts and culture. Specifically, we refer to Confucius, that shared his philosophy across the Chinese territory. The Zhou justified its authority and power by the "Mandate of Heaven," in that the Gods supported them to rule and prosper.
