The correct answer is: d) All of the above

In recent years, there has been an increase in the number of districts in Arunachal Pradesh. This is primarily due to a focus on decentralized administration, ethnic representation, and regional development.

Decentralized administration is the process of delegating power and authority from the central government to local governments. This can be done by creating new local governments, or by giving more power to existing local governments. Decentralized administration can help to improve efficiency and effectiveness of government services, and it can also help to promote local democracy and participation.

Ethnic representation is the process of ensuring that all ethnic groups are represented in government. This can be done by creating electoral districts that are specifically designed to represent ethnic minorities, or by giving ethnic minorities special representation in the legislature. Ethnic representation can help to promote peace and stability in a multi-ethnic society, and it can also help to ensure that the government is responsive to the needs of all its citizens.

Regional development is the process of promoting economic growth and development in a particular region. This can be done by investing in infrastructure, education, and healthcare, or by providing tax breaks and other incentives to businesses. Regional development can help to reduce poverty and inequality, and it can also help to improve the quality of life for people living in the region.

The increase in the number of districts in Arunachal Pradesh is a positive development that will help to improve the lives of the people of the state. Decentralized administration, ethnic representation, and regional development are all important aspects of good governance, and they will all help to make Arunachal Pradesh a more prosperous and equitable state.
