Explanation: The question requires identifying the odd one out among the given options, which are all names of Indian states. The classification criterion here is based on the historical formation of these states.
Bihar, Manipur, and Nagaland are all original states of India, meaning they were established at the time of India's independence in 1947 or shortly thereafter. These states have not undergone any significant changes in their boundaries or status since their formation. They are part of the original set of states that were created based on linguistic and cultural criteria.
Andhra Pradesh, however, is different. It was originally part of a larger state called Andhra Pradesh, which was formed in 1953. In 2014, this state was bifurcated into two separate states: Telangana and the new Andhra Pradesh. This recent reorganization makes Andhra Pradesh unique among the options provided, as it is the only state that has been formed through the division of a larger state.
The concept of state formation and reorganization in India is an important aspect of political geography and history. It involves understanding the historical context of state creation, the reasons behind the formation of new states, and the impact of such changes on the political landscape of the country. The bifurcation of Andhra Pradesh is a significant event in recent Indian history, reflecting the ongoing process of state reorganization based on linguistic, cultural, and administrative considerations.
In summary, the correct answer is Andhra Pradesh because it is the only state among the options that was formed through the division of a larger state, distinguishing it from the other original states listed. This question tests the understanding of the historical and political context of state formation in India.
