The Constitution of India serves as the fundamental law of the country and has several functions. Option 1 states that one of the functions of the Constitution is to ensure the participation of good people in politics. However, this statement is incorrect. The Constitution does not directly aim to ensure the participation of "good people" in politics. Instead, it lays down the framework and principles for the functioning of the government and the rights and obligations of its citizens.

Option 2 correctly states that the Constitution guarantees a set of rights to citizens. These rights include fundamental rights such as freedom of speech, equality, and the right to life and liberty.

Option 3 correctly states that the Constitution defines the power of the different organs of the government. It establishes a system of checks and balances and clearly demarcates the powers and functions of the legislature, executive, and judiciary.

Option 4 correctly states that the Constitution aims to create conditions for a just society. It sets forth the principles of social justice, equality, and the welfare of the people.

In conclusion, option 1 is not a function of the Constitution, as it does not focus on ensuring the participation of specific individuals in politics.
