Explanation: The question pertains to the recent news about the return of a specific tribe to Mizoram from Tripura. To understand this, it is essential to delve into the context of the Bru tribe and their historical displacement.
The Bru tribe, also known as Reang, is an ethnic group that originally hails from Mizoram. However, due to conflicts and violence in the 1990s, a significant portion of the Bru population was displaced and sought refuge in Tripura. This displacement led to a large number of Bru people living in camps in Tripura for over two decades.
In recent years, there have been concerted efforts by the government and various organizations to facilitate the return of the Bru people to their homeland in Mizoram. This process involves ensuring the safety and security of the returning Bru population, as well as addressing the socio-economic challenges they might face upon their return.
The other options provided in the question do not fit the context of the question. The Mizo tribe is the predominant ethnic group in Mizoram and has not been displaced to Tripura. The Santhals are primarily found in the states of Jharkhand, West Bengal, Odisha, and Bihar, and are not associated with Mizoram or Tripura. The Bodo tribe is mainly found in Assam and does not have a significant presence in Mizoram or Tripura.
Therefore, the correct answer is the Bru tribe, as they are the ethnic group that has been in the news for their return to Mizoram from Tripura. This situation highlights the complex issues of tribal displacement, conflict resolution, and the efforts to reintegrate displaced communities into their original homelands. Understanding such tribal movements and their socio-political implications is crucial for comprehending the demographic and cultural dynamics of the northeastern states of India.
