The source of political power in India is option 4, "We, the People." In a democratic country like India, the power ultimately lies with the citizens. This means that the people of India have the authority to elect their leaders and pass laws through the process of voting. The Constitution, option 1, is a framework that ensures the democratic functioning of the government, but it is the people who empower the Constitution. While the Parliament, option 2, and State Legislatures, option 3, have a significant role in the governance of the country, they derive their power from the people who elect their representatives. Therefore, it can be said that the ultimate source of political power in India lies with the people, as they have the ability to make decisions and choose their leaders.
