Option 1 -> The British Constitution contributed the parliamentary system and rule of law to India, but not the Directive Principles.
Option 2 -> The French Constitution inspired ideals of Liberty, Equality, and Fraternity in the Preamble, not the Directive Principles.
Option 3 -> The Irish Constitution of 1937 contains "Directive Principles of Social Policy" which served as the model for India's Directive Principles of State Policy.
Option 4 -> The Canadian Constitution provided the framework for federalism and distribution of powers, but not the Directive Principles.
Hence, Irish Constitution -> The Directive Principles of State Policy in Part IV of the Indian Constitution were directly inspired by the Directive Principles of Social Policy found in the Irish Constitution (1937), which laid down guidelines for the state to establish social and economic democracy -> correct
