Explanation:

- Option 1: Fundamental Rights

- Fundamental Rights are enshrined in Part III of the Indian Constitution. They secure civil liberties such as equality, freedom, and rights against exploitation, directly reflecting the ideals of Justice, Liberty, and Equality mentioned in the Preamble.

- Option 2: Directive Principles of State Policy

- Found in Part IV, these principles aim to establish social and economic democracy, promoting the welfare state, which also echoes the Preamble's ideals but are not enforceable by courts.

- Option 3: Fundamental Rights, Directive Principles of State Policy, and Fundamental Duties

- This option is comprehensive, as all three elements together elaborate on the Preamble. Fundamental Duties (Part IVA) were added to emphasize citizen responsibilities, contributing to Preamble ideals.

- Option 4: Nowhere else in the text of Indian Constitution

- Incorrect, as several sections of the Constitution strive to fulfill the Preamble’s goals.

- Correct Answer: Option 3: Fundamental Rights, Directive Principles of State Policy, and Fundamental Duties

They collectively give detailed expressions to the Preamble's objectives within the Constitution.
