The Fundamental Rights enshrined in the Indian Constitution were inspired by and modeled after the Bill of Rights in the United States Constitution. The Bill of Rights, which consists of the first ten amendments to the U.S. Constitution, guarantees individual freedoms such as freedom of speech, religion, and due process. These principles were incorporated into the Indian Constitution during its drafting, ensuring that citizens of India enjoy similar protections.
Here's why the other options are incorrect:
- Option (1): Ireland: While Ireland has a strong tradition of human rights, its constitution was not the primary source for the Fundamental Rights in the Indian Constitution.
- Option (2): Britain: Although India was formerly a British colony, the British Constitution does not have a direct influence on the Fundamental Rights in the Indian Constitution. Instead, the Indian Constitution draws more heavily from the U.S. Constitution.
- Option (3): Germany: Germany's constitution, particularly the Basic Law, includes robust human rights provisions, but it was not the primary source for the Fundamental Rights in the Indian Constitution.
- Option (4): United States of America: This is the correct answer, as the Fundamental Rights in the Indian Constitution are directly inspired by the Bill of Rights in the U.S. Constitution.
