Explanation: In the context of Indian administrative divisions, it is crucial to understand the distinction between states and Union Territories. States in India have their own governments and legislative assemblies, while Union Territories are governed directly by the Union Government, typically through a Lieutenant Governor.
Sikkim, located in the northeastern part of India, became the 22nd state of India on May 16, 1975, after a referendum in which the people of Sikkim voted to merge with India. Prior to this, Sikkim was a protectorate of India, with a monarchy and a legislative assembly. The merger transformed Sikkim into a state with its own government and legislative assembly, making it distinct from Union Territories.
Union Territories, on the other hand, are administrative divisions that do not have their own state governments. They are governed directly by the Union Government, which appoints a Lieutenant Governor to oversee the administration. Examples of Union Territories include Puducherry, Dadra and Nagar Haveli, and Delhi. These territories have varying degrees of autonomy, but they are ultimately under the direct control of the Union Government.
It is important to note that while some Union Territories have partial self-governance through elected legislative assemblies, they still fall under the direct administration of the Union Government. This is a key difference from states, which have full autonomy in their governance.
In summary, Sikkim is a state with its own government and legislative assembly, while the other options listed (Puducherry, Dadra and Nagar Haveli, and Delhi) are Union Territories governed directly by the Union Government. Therefore, Sikkim is the correct answer as it is not a Union Territory.
