Explanations:The outer Himalayas, also known as the Siwalik Range, are the southernmost part of the Himalayan mountain system. They form a natural boundary between the Indian subcontinent and the Tibetan Plateau. The outer Himalayas extend from Jammu and Kashmir in the west to Arunachal Pradesh in the east. This range is characterized by relatively low, discontinuous hills and ridges, which are composed of unconsolidated gravel and sand.
Arunachal Pradesh is the easternmost state of India and is part of the Himalayan range. It shares borders with Bhutan, China, and Myanmar. The state is known for its diverse topography, which includes high mountains, deep valleys, and dense forests. The Himalayan range plays a significant role in the geography of the region, influencing climate, biodiversity, and human settlement patterns.
It is important to note that while Bhutan, Dhaka (the capital of Bangladesh), and Myanmar are all located in the general region of the Himalayas, they are not part of the Indian states. Bhutan is an independent country, Dhaka is the capital of Bangladesh, and Myanmar is a neighboring country to India. Therefore, the correct answer to the question is Arunachal Pradesh, as it is the easternmost state of India and part of the outer Himalayas.
