The rise of insurgency movements in some parts of Arunachal Pradesh has been a challenge for the state government and security forces. These movements are often driven by:

Ethnic separatism
Perceived lack of development
External influences
All of the above

The correct answer is: d) All of the above

Ethnic separatism is a major factor in the rise of insurgency movements in Arunachal Pradesh. The state is home to a diverse range of ethnic groups, many of which have a long history of conflict with each other. These groups often feel that they have been marginalized by the central government and that their interests have been ignored. This has led to a sense of resentment and alienation, which has in turn fueled the rise of insurgency movements.

Perceived lack of development is another major factor in the rise of insurgency movements in Arunachal Pradesh. The state is one of the poorest in India, and many people feel that they have not benefited from the state’s economic growth. This has led to a sense of frustration and despair, which has in turn made people more susceptible to the appeal of insurgency movements.

External influences can also play a role in the rise of insurgency movements. In the case of Arunachal Pradesh, China has been accused of providing support to some of the state’s insurgent groups. This support has helped to prolong the conflict and make it more difficult to resolve.

In conclusion, the rise of insurgency movements in Arunachal Pradesh is a complex issue with a number of contributing factors. Ethnic separatism, perceived lack of development, and external influences are all important factors that have contributed to the rise of these movements.
