Exp) Option b is the correct answer. The Indian Constitution is unique in its contents and spirit. The Constitution of India has several salient features that distinguish it from the Constitutions of the other countries.

Options 1, 3 and 5 are correct. Three-tier Government: Originally, the Indian Constitution, like any other federal Constitution, provided for a dual polity and contained provisions with regard to the organisation and powers of the Centre and the states. Later, the 73rd and 74th Constitutional Amendment Acts (1992) have added a thirdtier of Government (i.e., local) which is not found in any other Constitution of the world. Blend of Rigidity and Flexibility: The Constitution of India is neither rigid nor flexible, but a synthesis of both. Some provisions of the Constitution can be amended by a simple majority of the Parliament in the manner of ordinary legislative process. Some other provisions can be amended by a special majority of the Parliament and with the ratification by half of the total states. Single Citizenship: Though the Indian Constitution is federal and envisages a dual polity (Centre and states), it provides for only a single citizenship, that is, the Indian citizenship.

Options 2 and 4 are incorrect. The doctrine of sovereignty of Parliament is associated with the British Parliament, while the principle of judicial supremacy with that of the American Supreme Court. The framers of the Indian Constitution have preferred a proper synthesis between the British principle of parliamentary sovereignty and the American principle of judicial supremacy. Constitutional conventions are often thought of as “unwritten” but sometimes conventions are recorded in writing. They play a key role in British Political system due to uncodified nature of British constitution. Indian Constitution is a very comprehensive, elaborate and detailed document. The role of convention is less acknowledged in Indian Political setup.
