Explanations:The Mishmi, Abor, Miri, and Dafla ranges are significant geographical features located in the northeastern state of Arunachal Pradesh, India. These ranges are part of the Himalayan mountain system and are known for their unique biodiversity and cultural significance. The Mishmi range, for instance, is located in the eastern part of Arunachal Pradesh and is home to the Mishmi people, who have a rich cultural heritage. The Abor range, also known as the Adi Hills, is located in the central part of the state and is inhabited by the Adi people. The Miri range, also known as the Idu-Mishmi Hills, is located in the eastern part of the state and is home to the Idu-Mishmi people. The Dafla range, also known as the Tangsa Hills, is located in the southeastern part of the state and is inhabited by the Tangsa people.
These ranges are not only important for their geographical features but also for their cultural and ecological significance. The Mishmi, Abor, Miri, and Dafla ranges are home to a variety of flora and fauna, many of which are endemic to the region. The ranges also play a crucial role in the traditional livelihoods of the local communities, who depend on the forests and rivers for their sustenance.
It is important to note that these ranges are not located in other northeastern states such as Meghalaya, Assam, or Sikkim. Meghalaya is known for its Khasi, Jaintia, and Garo hills, while Assam is known for the Brahmaputra Valley and the Barail Range. Sikkim, on the other hand, is known for the Kanchenjunga range and other Himalayan peaks. Therefore, the correct answer is Arunachal Pradesh, as it is the only state that contains the Mishmi, Abor, Miri, and Dafla ranges.
