Explanations:
India is a federal union comprising 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 to identify the odd one out among the given options, where the odd one is not a state.
Bihar, Odisha, and Gujarat are all recognized states in India. Each of these states has its own distinct culture, language, and administrative structure. Bihar is located in the eastern part of India, Odisha is in the eastern coastal region, and Gujarat is in the western part of the country.
Bombay, however, is not a state. It was the former name of the city of Mumbai, which is now the capital of the state of Maharashtra. The name change from Bombay to Mumbai occurred in 1995, reflecting a shift in the cultural and political landscape of the region. Mumbai is a major metropolitan city and a significant economic hub in India, but it is not a state.
The question tests the knowledge of current administrative divisions in India and the ability to distinguish between states and other administrative entities. It is important to be aware of the historical context and changes in the names and statuses of regions within India to correctly identify the current states.
In summary, the correct answer is "Bombay" because it is not a state but a city within the state of Maharashtra. The other options, Bihar, Odisha, and Gujarat, are all current states in India.
