A good section of people from the Reang community have taken shelter in…

Concept: Ethnic or communal conflict within a state can trigger large-scale displacement of a minority community into a neighbouring state, where the displaced group shelters in relief camps until a formal repatriation or resettlement agreement is reached. Current-affairs and state-GK questions on such displacements test whether the source state (where the conflict arose) and the host state (where refuge was taken) are correctly matched from among several similar Northeast Indian states.

Application: In 1997, ethnic tension between the Mizo majority and the Reang (also called Bru) minority in Mizoram escalated sharply after the killing of a Mizo forest official, an act attributed to a Bru insurgent group. The backlash triggered a mass exodus in which tens of thousands of Reang/Bru people fled Mizoram and took shelter in relief camps set up in Tripura, mainly in the Kanchanpur and Panisagar areas of North Tripura district, where a large number of them remained for over two decades.

Cross-check: This is corroborated by the Government of India's later repatriation process: the 2018 quadripartite agreement and the final 2020 Bru-Reang Resettlement Agreement — signed by the Centre, the Mizoram and Tripura governments, and Bru representative bodies — were framed specifically to resettle people who had migrated from Mizoram to Tripura, independently confirming Mizoram as the state of origin among the options offered.

Hence, the correct answer is Mizoram.
