Which of the following is a major cause of the French Revolution?

The middle class, also known as the bourgeoisie, was growing in size and wealth in the 18th century. They were frustrated by their lack of political power and by the privileges enjoyed by the nobility and clergy. The American Revolution, which overthrew a monarchy and established a republic, inspired the French middle class to demand similar changes in their own country.

The decline of the monarchy was a result of the French Revolution, not a cause of it. The Seven Years' War was a costly war that contributed to the financial problems of the French monarchy, but it was not a major cause of the Revolution. The American Revolution did not directly cause the French Revolution, but it did inspire the French middle class to demand change.
