The correct option is 1, 2, and 3, as all three parts of the Indian Constitution reflect principles from the Universal Declaration of Human Rights (UDHR). The Preamble embodies the fundamental values of justice, liberty, equality, and fraternity, which align with the UDHR's emphasis on human dignity and rights. The Directive Principles of State Policy articulate the state's responsibility to ensure social and economic welfare, which is consistent with the UDHR's call for social security and an adequate standard of living. Finally, the Fundamental Duties encourage citizens to respect the rights and freedoms of others, fostering a culture of human rights awareness and responsibility in line with the spirit of the UDHR. This holistic approach reinforces the constitutional commitment to upholding human rights in India, which is relevant for UPSC aspirants in understanding the integration of international human rights norms into domestic law.
