The correct answer is: d) All of the above.
The Inner Line Permit (ILP) system is a system of restricted entry into certain areas in India. The system was first introduced in 1873 in the Naga Hills and was later extended to other areas, including Arunachal Pradesh. The ILP system is intended to protect the tribal peoples of these areas from the negative effects of contact with outsiders.
The ILP system regulates entry and stay of outsiders in Arunachal Pradesh. Outsiders, including Indian citizens, need to obtain an ILP before entering the state. The ILP system also protects tribal land rights in Arunachal Pradesh. Land in Arunachal Pradesh is owned by the tribal peoples and cannot be sold or leased to outsiders. The ILP system also helps to preserve the cultural identity of the tribal peoples of Arunachal Pradesh. The system restricts the entry of outsiders into the state, which helps to protect the tribal peoples from the negative effects of contact with outsiders.
The ILP system has been controversial since its inception. Some people argue that the system is discriminatory and that it prevents outsiders from accessing the natural resources of Arunachal Pradesh. Others argue that the system is necessary to protect the tribal peoples of Arunachal Pradesh from the negative effects of contact with outsiders.
The ILP system is currently under review by the Indian government. The government is considering whether to make the system more flexible or to abolish it altogether.
