Which of the following state is not created from the state of Assam?

NCERT (2026-27): “Demands for autonomy … At independence the entire region except Manipur and Tripura comprised the State of Assam. Demands for political autonomy arose when the non-Assamese felt that the Assam government was imposing Assamese language on them. There were opposition and protest riots throughout the State. Leaders of the major tribal communities wanted to separate from Assam. They formed the Eastern India Tribal Union which later transformed into a more comprehensive All Party Hill Leaders Conference in 1960. They demanded a tribal State to be carved out of Assam. Finally instead of one tribal State, several States got carved out of Assam. At different points of time the Central Government had to create Meghalaya, Mizoram and Arunachal Pradesh out of Assam. Tripura and Manipur were upgraded into States too.

Sikkim’s merger … At the time of independence, Sikkim was a ‘protectorate’ of India. It meant that while it was not a part of India, it was also not a fully sovereign country. Sikkim’s defence and foreign relations were looked after by India, while the power of internal administration was with the Chogyal, Sikkim’s monarch. This arrangement ran into difficulty as the Chogyal was unable to deal with the democratic aspirations of the people. An overwhelming majority of Sikkim’s population was Nepali. But the Chogyal was seen as perpetuating the rule of a small elite from the minority Lepcha-Bhutia community. The anti-Chogyal leaders of both the communities sought and got support from the government of India. The first democratic elections to Sikkim assembly in 1974 were swept by Sikkim Congress which stood for greater integration with India. The assembly first sought the status of ‘associate state’ and then in April 1975 passed a resolution asking for full integration with India. This was followed by a hurriedly organised referendum that put a stamp of popular approval on the assembly’s request. The Indian Parliament accepted this request immediately and Sikkim became the 22nd State of the Indian union.…

Creation of new states … Another major reorganisation of states took place in the north-east in 1972. Meghalaya was carved out of Assam in 1972. Manipur and Tripura too emerged as separate states in the same year. The states of Mizoram and Arunachal Pradesh came into being in 1987. Nagaland had become a state much earlier in 1963.…”
