The correct answer is: a) Fifth Schedule Areas.
The Fifth Schedule of the Indian Constitution provides special provisions for the administration and control of Scheduled Areas and Scheduled Tribes. The Fifth Schedule Areas are those areas which are inhabited by a majority of Scheduled Tribes and where the tribal people are not adequately represented in the government. The Fifth Schedule Areas are administered by the Governor of the state, who is assisted by a Tribes Advisory Council.
The majority of tribal areas in Andhra Pradesh fall under the Fifth Schedule. These areas include the districts of Adilabad, East Godavari, Guntur, Khammam, Krishna, Kurnool, Mahbubnagar, Nalgonda, Prakasam, Ranga Reddy, Visakhapatnam, Vizianagaram, and West Godavari.
The Sixth Schedule of the Indian Constitution provides special provisions for the administration and control of Scheduled Areas and Scheduled Tribes in the northeastern states. The Sixth Schedule Areas are those areas which are inhabited by a majority of Scheduled Tribes and where the tribal people have a distinct culture and way of life. The Sixth Schedule Areas are administered by the Governor of the state, who is assisted by a Regional Council.
No Schedule Areas are those areas which are not covered by the Fifth Schedule or the Sixth Schedule. These areas are administered by the state government in the same way as other areas of the state.
Protected Areas are those areas which are reserved for the conservation of wildlife. Protected Areas include national parks, sanctuaries, and tiger reserves.
