In which year was Marie Antoinette executed?

Correct answer: 1793

The direct answer is C: 1793. Marie Antoinette, the queen of France and wife of Louis XVI, was executed by guillotine in 1793 during the radical phase of the Revolution. Option A, 1789, was the year the Revolution began with events such as the meeting of the Estates-General and the storming of the Bastille; she was not executed then. Option B, 1791, was the year of the Constitution and the royal family’s attempted flight, not her execution. Option C is correct. Option D, 1804, was the year Napoleon became emperor, long after Marie Antoinette’s death. A useful sequence is: Revolution begins in 1789, constitutional changes occur in 1791, the queen is executed in 1793, and Napoleon becomes emperor in 1804. This prevents confusion between important dates.
