The correct answer is: All of the above.
The Inner Line Permit (ILP) system is a system of travel restrictions in force in some parts of India. The system was introduced in the 19th century to protect tribal areas from outside influence. The ILP system requires all non-tribal people to obtain a permit from the government before entering these areas.
The ILP system is in place in the following states and union territories of India:
- Arunachal Pradesh
- Nagaland
- Mizoram
- Manipur
- Sikkim
- Ladakh
The ILP system is meant to achieve the following objectives:
- Regulate tourism: The ILP system is meant to regulate tourism in tribal areas. This is to ensure that the influx of tourists does not disturb the traditional way of life of the tribal people.
- Protect tribal areas: The ILP system is meant to protect tribal areas from outside influence. This is to ensure that the tribal people are able to preserve their culture and traditions.
- Preserve cultural traditions: The ILP system is meant to preserve the cultural traditions of the tribal people. This is to ensure that the tribal people are able to continue living their traditional way of life.
The ILP system has been criticized by some people who argue that it is discriminatory and that it prevents people from accessing certain parts of India. However, the government of India has defended the ILP system, arguing that it is necessary to protect the tribal people and their way of life.
