Correct Option (A):
The Directive Principles of State Policy (DPSP), enshrined in Part IV (Articles 36-51) of the Constitution of India, explicitly declare the ideal of a Welfare State. Article 38, in particular, directs the State to strive to promote the welfare of the people by securing and protecting a social order in which justice-social, economic, and political-shall inform all the institutions of national life. Although non-justiciable, these principles are fundamental in the governance of the country and guide the State in making laws and policies aimed at achieving social and economic democracy and establishing a welfare state.
Incorrect Options:
Option (2) Fundamental Rights: Fundamental Rights, contained in Part III of the Constitution, guarantee civil and political rights to individuals and impose limitations on the State's power. While crucial for a democratic society, they primarily focus on individual liberties and do not directly declare the ideal of a welfare state, which involves positive obligations of the state to ensure social and economic well-being.
Option (3) Preamble: The Preamble outlines the objectives and guiding philosophy of the Constitution, including justice, liberty, equality, and fraternity. It reflects the spirit and aspirations of a welfare state (e.g., "socialist, secular"), but it is an introductory statement and not the part that explicitly declares or details the operational ideal of a welfare state.
Option (4) Seventh Schedule: The Seventh Schedule deals with the distribution of legislative powers between the Union and State governments, listing subjects under the Union List, State List, and Concurrent List. It is concerned with the administrative and legislative framework of the federal system, not with the declaration of the ideal of a welfare state.
