The correct answer is A. The French Revolutionary period was the period when the French people put an end to absolute monarchy.
The French Revolution was a social and political conflict, with various periods of violence, which convulsed France and, by extension of its implications, other European nations that faced supporters and opponents of the system known as the Old Regime, characterized by a centralized and absolutist State, entirely dominated by the figure of the King of France. It began with the self-proclamation of the Third State as a National Assembly in 1789 and ended with the coup d'état of Napoleon Bonaparte in 1799.
Although after the First Republic fell after the coup d'état of Napoleon Bonaparte, the political organization of France during the 19th century oscillated between republic, empire and constitutional monarchy, the truth is that the revolution marked the final end of feudalism and absolutism in France, and gave birth to a new regime where the bourgeoisie, supported sometimes by the popular masses, became the dominant political force in the country.
