The correct answer is: A. The French Revolution, 1789.
The ideals of liberty, equality, and fraternity are the foundation of the French Revolution. They were first expressed in the Declaration of the Rights of Man and of the Citizen, which was adopted by the National Assembly on August 26, 1789. The Declaration states that all men are born free and equal in rights, and that they have the right to life, liberty, and property. It also states that the purpose of government is to protect these rights.
The ideals of liberty, equality, and fraternity were also adopted by the Indian Constitution. The Preamble to the Constitution states that India is a sovereign, socialist, secular, democratic republic. It also states that India is committed to securing justice, liberty, equality, and fraternity for all its citizens.
The ideals of liberty, equality, and fraternity are essential for a just and democratic society. They are the foundation of human rights and the rule of law. They are also the foundation of peace and progress.
The other options are incorrect because they do not represent the ideals of liberty, equality, and fraternity. The Russian Revolution was a communist revolution, and the Irish Revolution was a nationalist revolution. Both of these revolutions were based on different ideals than the French Revolution.
