The rationality behind special arrangements for only four states: Assam, Meghalaya, Tripura and Mizoram under the sixth schedule of the Indian constitution is:

The correct answer is option 2 . Key Points The sixth schedule of the constitution deals with the administration of the tribal areas in the four northeastern states of Assam, Meghalaya, Tripura and Mizoram. The rationality behind the special arrangement in respect of only these four States lies in the following: The tribes in Assam, Meghalaya, Tripura and Mizoram have not assimilated much the life and ways of the other people in the states. These areas have hitherto been anthropological specimens. The tribal people in other parts of India have more or less adopted the culture of the majority of people in whose midst they live. The tribes in Assam Meghalaya Tripura and Mizoram on the other hand still have their roots in their own culture and Customs and civilization. These areas are, therefore, treated differently by the constitution and a sizable amount of autonomy has been given to the people for self-government. Additional Information ​The various features of Administration content in the sixth schedule are as follows : The tribal areas in the four states of Assam Meghalaya Tripura and Mizoram have been constituted as autonomous districts but they do not fall outside the executive authority of the state concerned. The Governor is empowered to organise and reorganize the autonomous district. If there are different tribes in an autonomous district the government can divide the district into several autonomous regions. Each autonomous district has a district Council consisting of 30 members of whom are nominated by the Governor and the remaining 26 are elected on the basis of adult franchise. Each autonomous region also has a separate regional Council. The district and regional councils administer the area under their jurisdiction. The district and regional councils within their territorial jurisdiction can constitute village councils for courts of the trial of suits and cases between the tribes. The provisions of the Sixth Schedule provide certain financial powers to the District and Regional Councils. They are empowered to prepare a budget for their respective councils.
