The concept of Welfare State is found in the Indian Constitution in the

The concept of Welfare State is found in the Directive Principles of State Policy (DPSP) in the Indian Constitution.

Explanation:

• Directive Principles of State Policy (DPSP): These are guidelines for the government to work towards establishing a social and economic order that ensures justice, equality, and welfare for all citizens. The concept of a welfare state is explicitly mentioned in the DPSPs, particularly Articles 38 and 39.

Why other options are incorrect:

• Fundamental Duties: Fundamental Duties are listed in Article 51A of the Constitution. They outline the responsibilities of citizens towards the nation. While they promote civic values, they do not explicitly address the concept of a welfare state.
• Preamble: The Preamble outlines the objectives and philosophy of the Indian Constitution. It mentions the goal of securing social, economic, and political justice. However, the term "welfare state" is not explicitly used there. The DPSPs elaborate on the concept of a welfare state.
• Fundamental Rights: Fundamental Rights, enshrined in Part III of the Constitution (Articles 12-35), guarantee certain freedoms and rights to citizens. These rights are essential for individual liberty and equality. However, they are not directly related to the concept of a welfare state, which focuses on the government's role in promoting social and economic well-being.
