The correct option is Ireland.
Explanation
The Indian Constitution incorporates various features drawn from different global constitutions. The Directive Principles of State Policy (DPSP), enshrined in Part IV (Articles 36-51), represent the socio-economic goals of the state.
- Ireland: The concept of Directive Principles of State Policy was borrowed from the Irish Constitution (1937). The framers of the Irish Constitution had originally adopted this concept from the Spanish Constitution. Dr. B.R. Ambedkar described these principles as a "novel feature" of the Indian Constitution.
- Canada: The Canadian Constitution is the source for the federal scheme with a strong Centre, the vesting of residuary powers in the Centre, the appointment of State Governors by the Centre, and the advisory jurisdiction of the Supreme Court.
- France: The ideals of Liberty, Equality, and Fraternity in the Preamble, as well as the concept of a Republic, were borrowed from the French Constitution.
- USA: The Constitution of the United States inspired features such as Fundamental Rights, independence of the judiciary, judicial review, impeachment of the President, and the removal of Supreme Court and High Court judges.
Key Takeaway: The Directive Principles of State Policy were borrowed from the Irish Constitution, reflecting the influence of the Fabian socialist movement and the concept of a welfare state.
