The Inner Line Permit (ILP) system in Arunachal Pradesh is a legacy of the:

Bengal Eastern Frontier Regulations, 1873
Government of India Act, 1935
Constitution of India
North-Eastern Areas (Reorganisation) Act, 1971

The correct answer is: a) Bengal Eastern Frontier Regulations, 1873.

The Inner Line Permit (ILP) system is a system of restricted travel in the northeastern states of India. It was introduced in the Bengal Eastern Frontier Regulations, 1873, to protect the indigenous people of the region from outside influences. The ILP system requires all non-indigenous people to obtain a permit from the government before entering the region.

The ILP system has been controversial since its inception. Some people argue that it is necessary to protect the indigenous people of the region, while others argue that it is a form of discrimination. The ILP system is currently being reviewed by the Indian government.

The other options are incorrect because:

  • The Government of India Act, 1935, is a law that established the Government of India. It does not mention the ILP system.
  • The Constitution of India, 1950, is the supreme law of India. It does not mention the ILP system.
  • The North-Eastern Areas (Reorganisation) Act, 1971, is a law that reorganized the northeastern states of India. It does not mention the ILP system.
