Explanations:The Indian Constitution, adopted in 1950, provides for the formation and reorganization of states through specific articles. Article 2 and Article 3 are the two primary articles that deal with the formation and reorganization of states in India.
Article 2 of the Indian Constitution is specifically designed to facilitate the formation of new states and the alteration of the areas, boundaries, or names of existing states. This article is crucial for the integration of territories into the Indian Union and the creation of new states. It requires a parliamentary resolution and the President's assent to bring about such changes.
On the other hand, Article 3 deals with the reorganization of existing states. It allows for the creation of new states within the territory of India, the alteration of the boundaries of any state, the separation of territory from any state, and the union of two or more states or parts of states. However, it does not cover the formation of new states from territories outside the existing states of India.
In the case of Sikkim, it was a separate kingdom before 1975. In 1975, Sikkim was integrated into India as a new state. This integration was achieved through the application of Article 2 of the Indian Constitution. The process involved a parliamentary resolution and the President's assent, as required by Article 2. The Sikkim (Statehood) Order, 1975, was issued under this article, which officially made Sikkim a part of India as its 22nd state.
Therefore, the correct answer is Article 2, as it is the constitutional provision that facilitated the formation of Sikkim as a new state in India in 1975. Understanding the distinction between Article 2 and Article 3 is crucial for comprehending the constitutional mechanisms for state formation and reorganization in India.
