A key resource for industrial development in Arunachal Pradesh is its:

Abundant natural resources
Highly skilled workforce
Extensive transport network
Large domestic market

The correct answer is (a) Abundant natural resources.

Arunachal Pradesh is a state in northeastern India. It is the largest state in the country by area, but it has a very small population. The state is rich in natural resources, including forests, minerals, and water. These resources have the potential to support a wide range of industries.

The state government has been working to develop the industrial sector in Arunachal Pradesh. In recent years, there has been some investment in the manufacturing sector, particularly in the production of food processing, paper, and cement. However, the state still has a long way to go to develop its industrial potential.

One of the main challenges facing industrial development in Arunachal Pradesh is the lack of infrastructure. The state has a poor road network and limited access to electricity. This makes it difficult for businesses to operate and export their products.

Another challenge is the lack of skilled workers. The state has a young population, but many young people are not trained in the skills that are needed by industries. The government is working to address this challenge by investing in education and training.

Despite the challenges, there are reasons to be optimistic about the future of industrial development in Arunachal Pradesh. The state has a number of advantages, including its abundant natural resources, its strategic location, and its young population. With the right investment and support, the state has the potential to become a major industrial hub in India.

Option (b), Highly skilled workforce, is not correct because the state has a young population, but many young people are not trained in the skills that are needed by industries. The government is working to address this challenge by investing in education and training.

Option (c), Extensive transport network, is not correct because the state has a poor road network and limited access to electricity. This makes it difficult for businesses to operate and export their products.

Option (d), Large domestic market, is not correct because the state has a very small population.
