The formation of new states in Northeast India, such as Nagaland, Meghalaya, and Mizoram, was a result of:

The correct answer is: a) Demands for greater autonomy by tribal communities.

The formation of new states in Northeast India, such as Nagaland, Meghalaya, and Mizoram, was a result of the demands for greater autonomy by tribal communities in the region. These communities felt that they were being neglected by the central government and that their culture and traditions were being threatened. They also felt that they were not being given a fair share of the resources of the region.

The formation of these new states was a way of addressing these concerns and giving the tribal communities a greater say in their own affairs. It has also helped to promote peace and stability in the region.

Here is a brief explanation of each option:

• a) Demands for greater autonomy by tribal communities: The tribal communities in Northeast India have long felt that they have been neglected by the central government. They have also felt that their culture and traditions are being threatened. As a result, they have been demanding greater autonomy for their regions. The formation of new states in Northeast India was a way of addressing these concerns and giving the tribal communities a greater say in their own affairs.
• b) Border disputes with neighboring countries: Northeast India shares borders with several neighboring countries, including China, Bangladesh, and Myanmar. These countries have often been accused of encroaching on Indian territory. This has led to border disputes between India and these countries. The formation of new states in Northeast India has not helped to resolve these disputes.
• c) Administrative reorganization: The Indian government has often reorganized the administrative divisions of the country. This has been done for a variety of reasons, including to improve efficiency, to promote development, and to address the concerns of minority groups. The formation of new states in Northeast India was part of a larger administrative reorganization of the country.
• d) Economic development strategies: The Indian government has often implemented economic development strategies in different parts of the country. These strategies have been designed to promote economic growth and development. The formation of new states in Northeast India was not part of any economic development strategy.
