Which of the following part of the Indian Constitution is related to the Directive Principles of State Policy?

The correct option is Part IV in the Indian Constitution.

The Directive Principles of State Policy (DPSP) are contained in Part IV of the Constitution of India, spanning from Article 36 to Article 51. These principles serve as constitutional guidelines and recommendations for the government (both central and state) to keep in mind while formulating laws, policies, and programs. The main objective of the Directive Principles is to establish a welfare state and promote social and economic justice for the citizens of India. Unlike Fundamental Rights, Directive Principles are non-justiciable, meaning they cannot be directly enforced by any court of law if a government fails to implement them.

To provide a complete educational overview, here is what the other parts mentioned in the options signify:
• Part III: Contains the Fundamental Rights (Articles 12 to 35) guaranteed to all citizens, which are justiciable in courts.
• Part V: Deals with the Union Government (Articles 52 to 151), covering the executive, legislative, and judicial branches at the central level.
• Part VI: Covers the State Governments (Articles 152 to 237), outlining the administration, executive, legislature, and judiciary at the state level.
