The watch words of the French Revolution were Liberty, Equality, and Fraternity.

Option 1, "Right, Liberty, and Equality," while containing some correct elements, does not include the important principle of Fraternity. Therefore, it is not the correct answer.

Option 2, "Liberty, Equality, and Justice," is close, but it fails to include Fraternity. Fraternity refers to the idea of brotherhood and solidarity among citizens, which was a fundamental concept during the French Revolution. Thus, this option is not the correct answer.

Option 4, "Rights, Equality, and Justice," also does not include the principle of Fraternity. Additionally, it exchanges Liberty for Rights, which is not the accurate term associated with the French Revolution.

The correct answer is option 3, "Liberty, Equality, and Fraternity." These three words encapsulate the core values and goals of the French Revolution. Liberty refers to the desire for personal and political freedom, Equality reflects the aim to dismantle social hierarchies and create a fair society, and Fraternity emphasizes the importance of unity and solidarity among citizens.
