One major challenge to economic development in Arunachal Pradesh is:

The correct answer is: a) Limited infrastructure.

Arunachal Pradesh is a landlocked state in north-eastern India. It is the largest state in the country by area, but it has a very small population. The state is sparsely populated and has a low level of economic development. One of the major challenges to economic development in Arunachal Pradesh is limited infrastructure. The state has a poor road network, and there is limited access to electricity and telecommunications. This lack of infrastructure makes it difficult for businesses to operate in the state, and it also makes it difficult for people to get around.

The other options are incorrect for the following reasons:

• Option b) Abundant skilled labor is incorrect because Arunachal Pradesh has a low level of education and skills development. The state has a high rate of illiteracy, and there are few opportunities for people to get an education or training. This lack of skills makes it difficult for people to find jobs, and it also makes it difficult for businesses to find skilled workers.
• Option c) Over-reliance on agriculture is incorrect because Arunachal Pradesh is not a major agricultural state. The state has a small agricultural sector, and it accounts for a small share of the state’s economy. The state’s economy is more reliant on services and government spending.
• Option d) Lack of natural resources is incorrect because Arunachal Pradesh has a number of natural resources, including forests, minerals, and hydropower. However, the state has not been able to develop these resources effectively, and they have not been a major driver of economic growth.
