Explanation: Mizoram, a state in northeastern India, is characterized by its diverse and intricate drainage systems. These systems are essential for understanding the geographical and hydrological features of the state. The drainage systems in Mizoram are primarily influenced by the topography and the monsoon climate, which results in a network of rivers and streams that drain the region.
The Khawthlangtuipui Drainage System is one of the significant drainage systems in Mizoram. The Khawthlangtuipui River originates in the southwestern part of Mizoram and flows southward, eventually forming a natural boundary with Bangladesh. This river is crucial for the southwestern region of Mizoram, as it not only drains the area but also serves as a geographical marker between Mizoram and Bangladesh.
The drainage systems in Mizoram are classified based on their location and the regions they drain. The Tlawng Drainage System, for instance, is located in the eastern part of Mizoram and is a tributary of the Barak River. The Chhimtuipui Drainage System is located in the central part of Mizoram and is significant for the central region. The Tuivawl Drainage System is located in the northern part of Mizoram and is important for the northern region.
Understanding the drainage systems in Mizoram is essential for comprehending the geographical and hydrological features of the state. The Khawthlangtuipui Drainage System, in particular, is significant due to its role in draining the southwestern part of Mizoram and forming a natural boundary with Bangladesh. This drainage system is a key feature in the geographical landscape of Mizoram and plays a crucial role in the state's hydrology and ecology.
In conclusion, the Khawthlangtuipui Drainage System is the correct answer as it accurately describes the drainage system that drains the southwestern part of Mizoram and forms a boundary with Bangladesh. This system is a vital component of Mizoram's geographical and hydrological landscape, highlighting the importance of understanding drainage systems in regional geography.
