Explanations:India is a federal union consisting of 28 states and 8 union territories. Each state has its own government and legislative assembly, while union territories are governed directly by the central government. The question asks which of the given options is not a state. To answer this, we need to understand the status of each option in the context of the Indian administrative structure.
Bihar is a state located in the eastern part of India. It has its own government and legislative assembly, making it a recognized state. Therefore, it is incorrect to say that Bihar is not a state.
Jammu is a region within the union territory of Jammu and Kashmir. Prior to 2019, Jammu and Kashmir was a single state, but it was bifurcated into two union territories: Jammu and Kashmir, and Ladakh. Jammu alone is not a state; it is part of the union territory of Jammu and Kashmir. Therefore, Jammu is the correct answer to the question as it is not a state.
Sikkim is a state located in the northeastern part of India. It became the 22nd state of India in 1975 after being a protectorate of India since 1950. Sikkim has its own government and legislative assembly, making it a recognized state. Therefore, it is incorrect to say that Sikkim is not a state.
Telangana is a state in India, formed on 2 June 2014 from the northern part of Andhra Pradesh. It has its own government and legislative assembly, making it a recognized state. Therefore, it is incorrect to say that Telangana is not a state.
In summary, the question tests the knowledge of the administrative divisions of India, specifically the distinction between states and union territories. Jammu is the correct answer because it is a region within a union territory, not a state on its own.
