Explanation:

This question asks about the source of the concept of Fundamental Duties in the Indian Constitution. (A) USA: The concept of Fundamental Rights in the Indian Constitution was inspired by the Bill of Rights in the US Constitution. However, the concept of Fundamental Duties was not taken from the USA. The document incorrectly indicated this option as the correct answer. Therefore, this option is factually incorrect. (B) Russia: The concept of Fundamental Duties was incorporated into the Indian Constitution by the 42nd Amendment Act of 1976, based on the recommendations of the Swaran Singh Committee. This concept was inspired by the Constitution of the erstwhile Union of Soviet Socialist Republics (USSR), which is now largely referred to as Russia. The USSR Constitution included a chapter on the rights and duties of citizens. This option is correct. (C) South Africa: The procedure for the amendment of the Constitution (Article 368) and the election of the members of the Rajya Sabha were borrowed from the South African Constitution. Fundamental Duties were not borrowed from South Africa. Therefore, this option is incorrect. (D) Canada: The concept of a federation with a strong center, the vesting of residuary powers in the center, the appointment of state governors by the center, and advisory jurisdiction of the Supreme Court were borrowed from the Canadian Constitution. Fundamental Duties were not borrowed from Canada. Therefore, this option is incorrect.
