Assam has a history of in-migration from:

Neighboring states
Bangladesh
Nepal
All of the above

The correct answer is: d) All of the above.

Assam has a long history of in-migration from neighboring states, Bangladesh, and Nepal. The first major wave of in-migration occurred in the 19th century, when people from neighboring states, such as Bengal and Bihar, migrated to Assam in search of work. This migration was largely due to the British colonial government’s policies, which encouraged the development of tea plantations in Assam. The tea plantations required a large workforce, and the British government recruited workers from neighboring states.

The second major wave of in-migration occurred in the 20th century, when people from Bangladesh migrated to Assam. This migration was largely due to the partition of India in 1947. The partition created two new countries, India and Pakistan. Assam was part of India, but it was located on the border with Pakistan. This made it a natural destination for people who were fleeing violence and persecution in Pakistan.

The third major wave of in-migration occurred in the late 20th century, when people from Nepal migrated to Assam. This migration was largely due to economic factors. Nepal is a relatively poor country, and many people have migrated to Assam in search of better opportunities.

The in-migration to Assam has had a significant impact on the state’s demographics. The population of Assam has increased rapidly in recent decades, and the state is now home to a diverse population of people from different ethnic and religious backgrounds. This diversity has sometimes led to tensions and conflict.

The in-migration to Assam has also had a significant impact on the state’s economy. The influx of new people has created a demand for new jobs and services. This has helped to boost the state’s economy. However, the in-migration has also put a strain on the state’s infrastructure.

The in-migration to Assam is a complex issue with a long history. It is an issue that has had a significant impact on the state’s demographics, economy, and society.
