Which option gives the correct causal chain of the outbreak?

Empty treasury → Estates-General → voting dispute → National Assembly → popular action

The governing concept is the connected development of a fiscal crisis into a constitutional and popular revolution. France’s treasury was weakened by expensive wars, debt and an unfair tax system, so Louis XVI called the Estates-General in 1789. The dispute over whether voting should be by estate or by individual representative exposed the political inequality of the old order. The Third Estate then declared itself the National Assembly, claiming to represent the nation. Popular action in Paris, including the storming of the Bastille, strengthened this challenge to royal authority. Therefore option A gives the correct sequence. Option B mixes unrelated dates and events, while C and D reverse the actual direction of the crisis.
