Answer:
The option that describes the impact of the idea of government as social contract on the French Revolution in 1789 is B. French citizens claimed their natural rights.
Step-by-step explanation:
The impact of the idea of government as social contract on the French Revolution in 1789 was that French citizens claimed their natural rights. This idea, popularized by Enlightenment philosophers such as John Locke and Jean Jacques Rousseau, emphasized that the government's power came from the consent of the governed and that citizens had the right to rebel against unjust rulers. This belief in natural rights and the social contract was a key factor in the overthrow of the monarchy and the establishment of a new government based on principles of liberty, equality, and fraternity.
