Explanation: India is a federal union comprising 28 states and 8 union territories. Each state has its own government and is a distinct political entity within the country. The states are further divided into districts, which are then divided into smaller administrative units such as tehsils, blocks, and villages.
The question asks which of the given options is not a state of India. To answer this, it is important to understand the current political divisions of India.
Bihar is a state located in the eastern part of India. It is known for its rich cultural heritage and historical significance, including being the birthplace of several religions and movements. Therefore, Bihar is indeed a state of India.
Jammu, on the other hand, is not a state but a part of the union territory of Jammu and Kashmir. The union territory of Jammu and Kashmir was formed after the reorganization of the state of Jammu and Kashmir in 2019. The misconception here is that students might think Jammu is a separate state, but it is not. Jammu is a region within the union territory, along with Kashmir and Ladakh.
Sikkim is a state of India. It became the 22nd state of India in 1975 after being a protectorate of India. Sikkim is known for its scenic beauty and is located in the northeastern part of the country, bordering Nepal, Bhutan, and Tibet.
Telangana is also a state of India. It was formed on 2 June 2014, after being separated from Andhra Pradesh. The creation of Telangana was a result of a long-standing demand for a separate state based on linguistic and cultural differences.
In conclusion, the correct answer is Jammu, as it is not a state but a part of the union territory of Jammu and Kashmir. Understanding the current political divisions of India is crucial for correctly identifying the states and union territories.
