The correct answer is option 'C' - Ireland.

The Directive Principles of State Policy (DPSP) in the Indian Constitution were indeed taken from the Constitution of Ireland. The DPSP are a set of guidelines and principles that the state is expected to keep in mind while formulating policies and making laws. They are not enforceable in court, but they serve as a moral and political compass for the government to work towards creating an ideal society.

The DPSP in the Indian Constitution were inspired by the Irish Constitution's "Directive Principles of Social Policy." The framers of the Indian Constitution, led by Dr. B.R. Ambedkar, admired the Irish Constitution for its emphasis on social justice, economic welfare, and the idea of a welfare state. They believed that incorporating similar principles into the Indian Constitution would help in the socio-economic development of the country.

Here are some key points about the DPSP in the Indian Constitution:

1. Aim: The DPSP aim to establish social, economic, and political justice in the country. They provide guidelines for the government to work towards the welfare of the people and the overall development of society.

2. Comprehensive Principles: The DPSP cover a wide range of areas, including social justice, economic welfare, international relations, governance, and environmental protection. They address various aspects of governance and strive for inclusive growth.

3. Social Justice: The DPSP emphasize the eradication of social inequalities, protection of marginalized communities, and promotion of equal opportunities for all citizens. They advocate for the abolition of untouchability, improvement in the status of women, and protection of the rights of children.

4. Economic Welfare: The DPSP focus on ensuring a just and equitable distribution of resources. They call for the elimination of poverty, promotion of rural development, and equitable distribution of wealth and resources.

5. Gandhian Principles: The DPSP also incorporate Gandhian principles, such as the promotion of cottage industries, decentralized planning, and the protection of the environment.

6. Limitations: While the DPSP serve as a guiding framework for the government, they are not enforceable in court. However, the Supreme Court has held that they are fundamental to the interpretation of laws and can influence judicial decisions.

In conclusion, the Directive Principles of State Policy in the Indian Constitution were borrowed from the Constitution of Ireland. They provide a set of guidelines for the government to work towards social, economic, and political justice in the country. Although not legally enforceable, they serve as an important moral and political compass for the government to create an inclusive and welfare-oriented society.
