Solution : The Correct option is the Forty-second Amendment Act of 1976 .

The Forty-second Amendment Act of 1976 amended the Indian Constitution to include the Fundamental Duties. This modification, which became effective on November 3, 1976, included a new Part IVA that contains a list of the eleven fundamental duties that Indian citizens are obligated to uphold. The Indian Constitution's guiding principles and the Swaran Singh Committee's 1976 recommendations served as the foundation for the notion of adding fundamental duties to the Indian Constitution.
