The correct answer is: a) Rural to urban migration within the state
Mizoram is a state in northeastern India with a population of over 1.1 million people. The state is predominantly rural, with over 60% of the population living in rural areas. However, there has been a significant increase in rural to urban migration in recent years. This is due to a number of factors, including the lack of economic opportunities in rural areas, the availability of better education and healthcare in urban areas, and the desire to improve one’s standard of living.
The influx of migrants from neighboring states is not a major pattern of migration in Mizoram. The state has a relatively small population and is not a major destination for migrants from other parts of India.
Emigration to other parts of India or abroad is also not a major pattern of migration in Mizoram. The state has a relatively low rate of emigration, and most people who do emigrate do so for educational or employment opportunities.
Large-scale seasonal migration is not a major pattern of migration in Mizoram. There is some seasonal migration within the state, but it is not on a large scale.
In conclusion, the major pattern of migration in Mizoram is rural to urban migration within the state. This is due to a number of factors, including the lack of economic opportunities in rural areas, the availability of better education and healthcare in urban areas, and the desire to improve one’s standard of living.
