Explanation: The Constitution (Sixty-ninth Amendment) Act, 1991, is a significant piece of legislation in the context of Delhi's governance and constitutional status. Prior to this amendment, Delhi was known as a Union Territory, which meant that it was directly governed by the central government. The amendment changed this status, declaring the Union Territory of Delhi to be formally known as the National Capital Territory of Delhi (NCTD).
The primary purpose of this amendment was to provide a more structured governance framework for the capital city. The NCTD was given a unique status that allowed it to have a greater degree of autonomy in its governance while still being under the direct control of the central government. This change was aimed at addressing the specific needs and challenges of the capital city, which is not only the seat of the central government but also a major metropolitan area with its own distinct administrative requirements.
The amendment was passed in 1991, which is why option B is the correct answer. It is important to note that this amendment did not change the administrative structure of Delhi significantly; rather, it was more about changing the nomenclature and providing a legal basis for the unique status of the capital city. The NCTD continues to be governed by a Lieutenant Governor appointed by the President of India, with the elected Chief Minister and the Council of Ministers assisting in the governance of the territory.
Understanding the historical context and the specific year of the amendment is crucial for students preparing for competitive examinations related to Delhi's governance and constitutional status. The amendment is a key point in the history of Delhi and its governance, and it is often tested in various competitive examinations, including the UPSC Civil Services, Delhi Police, and Delhi Civil Services exams.
