both statements are individually true, and statement II is the correct explanation of statement I. The Constitution of India is indeed a liberal Constitution, emphasizing democratic values, individual rights, and freedoms. Statement II clarifies that it achieves this liberal character by providing Fundamental Rights to individuals, which are essential elements of a liberal democratic framework, ensuring citizens' liberties and equal protection under the law.

The Unitary System of Government, where power is concentrated at the central level, ensures uniformity, efficiency, and quick decision-making in governance. This system allows for streamlined implementation of policies and laws without regional variations, leading to administrative simplicity. However, the Directive Principles of State Policy, while essential, are distinct principles in the Indian Constitution, guiding social and economic policies, irrespective of the system of government in place.

The Right to Property in India is recognized as a legal right under Article 300-A of the Indian Constitution. It means that individuals have the right to own and use property, and they cannot be deprived of their property except by authority of law. However, it is no longer a fundamental right, which means that the government can impose reasonable restrictions on property ownership. While individuals have legal protection for their property, it is subject to certain limitations defined by law.

India is a republic because the head of the state, the President, is elected by an electoral college for a fixed term of five years. This democratic process ensures that the highest office in the country is not hereditary but held through periodic elections, reflecting the nation's commitment to representative governance and equality.
