The correct answer is: Neighboring states.
Manipur is a state in northeastern India. It is bordered by the states of Nagaland to the north, Assam to the west, Mizoram to the south, and the country of Myanmar to the east. The majority of the population of Manipur is Meitei, followed by Nagas, Kukis, and other ethnic groups.
In-migration to Manipur occurs from the neighboring states of Nagaland, Assam, and Mizoram. The main reasons for in-migration are economic opportunities, education, and healthcare. The in-migrants are mostly from the lower economic strata and are looking for better opportunities in Manipur.
The in-migration has led to a number of challenges, including increased pressure on resources, social unrest, and environmental degradation. The government of Manipur is working to address these challenges by providing basic amenities to the in-migrants and by promoting harmony between the in-migrants and the locals.
The other options are incorrect because:
- Bangladesh is not a neighboring state of Manipur.
- Myanmar is a neighboring state of Manipur, but the in-migration from Myanmar is relatively low.
- Nepal is not a neighboring state of Manipur.
