The existence of more than one level of government in the country.
Explanation
Federalism is a system of government in which power is divided between a central authority and various constituent units of the country. It fundamentally entails a vertical distribution of power, creating a dual polity.
Option Analysis:
- The supremacy of the central government over state governments in all matters. is incorrect: The supremacy of the central government in all matters characterizes a unitary system. In a federal system, the Constitution divides powers between the Centre and the States, ensuring that the States have autonomy in their specific spheres (e.g., State List subjects).
- The existence of more than one level of government in the country. is correct: The primary signification of federalism is the existence of more than one level of government in the country. In India, this includes the Central Government, State Governments, and Local Self-Governments (Panchayats and Municipalities).
- The separation of powers between the legislature, executive, and judiciary. is incorrect: The separation of powers between the legislature, executive, and judiciary refers to the horizontal distribution of power among the organs of the state. While this is a feature of modern democracies, it is distinct from federalism, which refers to the vertical division of power.
- The direct election of the Prime Minister by the citizens. is incorrect: The method of electing the Prime Minister relates to the parliamentary or presidential nature of the democracy and the electoral system, not the federal structure.
Key Takeaway:
Federalism is defined by the vertical division of power, ensuring the existence of at least two tiers of government (Centre and States) with constitutionally defined authority.
