Explanation: The Purvanchal range is a significant geographical feature located in the northeastern part of India. It is a series of hills and ridges that stretch across several northeastern states, including Assam, Meghalaya, and Tripura. The term "Purvanchal" is derived from two Sanskrit words: "Purva," meaning "east," and "Anchal," meaning "region." This etymology accurately reflects the geographical location of the range, which is situated in the eastern part of India.
The Purvanchal range is distinct from the Himalayas, which are located in the northern part of India. While the Himalayas form a continuous chain of mountains along the northern border of India, the Purvanchal range is a series of smaller, discontinuous hills and ridges. The range is characterized by its diverse ecological and cultural landscape, supporting a wide variety of flora and fauna and being home to numerous indigenous communities.
The Purvanchal range plays a crucial role in the topography and climate of northeastern India. It influences the region's weather patterns, particularly the monsoon, and serves as a natural barrier that affects the movement of people and goods. Understanding the location and significance of the Purvanchal range is essential for comprehending the geographical and ecological diversity of northeastern India.
In summary, the Purvanchal range is located in the northeastern part of India, making option B the correct answer. This range is an important geographical feature that contributes to the unique landscape and biodiversity of the northeastern region.
