Explanations:The Naga hills are a significant geographical feature in northeastern India, forming a natural boundary between India and Myanmar. This mountain range is part of the larger Himalayan mountain system and plays a crucial role in the region's geography and climate. The Naga hills are not only a physical boundary but also a watershed, which means they serve as a dividing line for the drainage of water into different river systems.
Watersheds are important geographical features that determine the flow of water and, consequently, the distribution of water resources. In the case of the Naga hills, they form the watershed between the drainage systems of India and Myanmar. This means that the rivers originating from the Naga hills flow into different river systems on either side of the boundary, with some flowing into the Brahmaputra river system in India and others into the Irrawaddy river system in Myanmar.
It is essential to understand the geographical context of the Naga hills to correctly identify the neighboring country. The Naga hills are located in the northeastern part of India, specifically in the state of Nagaland. This region is characterized by its mountainous terrain and is part of the larger Himalayan mountain system. The Himalayas form the major boundary between India and China, while the Naga hills form the boundary between India and Myanmar.
Other mountain ranges and geographical features in the region, such as the Himalayas and the Ganges and Brahmaputra rivers, form the boundaries with other neighboring countries like Bhutan and Bangladesh. However, the Naga hills specifically form the watershed between India and Myanmar, making this the correct answer to the question.
