The correct answer is option 2: Quasi Federal. This means that the Indian Constitution has both federal and unitary features. In a federal system, power is divided between the central government and the state governments. In a unitary system, power is concentrated with the central government. The Indian Constitution embodies characteristics of both systems. While it establishes a federal structure with division of powers between the central government and the state governments, it also provides for a strong central authority that can intervene in the affairs of the states. The central government has the power to amend the Constitution, a feature typically found in unitary systems. However, the powers of the state governments are protected by the Constitution itself. Therefore, the Indian Constitution is considered to be quasi federal in nature.
