Eastern Terminal of East-West Corridor: Silchar

Explanation:
The East-West Corridor is one of the key National Highways in India, connecting the eastern and western parts of the country. It is designated as National Highway 37 (NH-37) and runs from Porbandar in Gujarat to Silchar in Assam, covering a distance of approximately 3,400 kilometers.

Silchar, located in the state of Assam, is the eastern terminal of the East-West Corridor. Let's understand why Silchar is the correct answer.

1. Definition of Eastern Terminal:
- The eastern terminal refers to the point where the East-West Corridor ends in the east and connects with other road networks or terminates altogether.
- In the context of the East-West Corridor, the eastern terminal is the last point of the corridor's route in the east.

2. Understanding the Options:
a) Shillong: Shillong is the capital of Meghalaya and is not directly connected to the East-West Corridor. It is not the eastern terminal.
b) Silvassa: Silvassa is the capital of Dadra and Nagar Haveli and is located in western India. It is not connected to the East-West Corridor. It is not the eastern terminal.
c) Silchar: Silchar is a town in the Cachar district of Assam. It is the last point of the East-West Corridor in the east and acts as the eastern terminal.
d) Singrauli: Singrauli is a town in the state of Madhya Pradesh and is not connected to the East-West Corridor. It is not the eastern terminal.

3. Conclusion:
Based on the above analysis, it is clear that Silchar is the correct answer as it is the eastern terminal of the East-West Corridor. The other options (Shillong, Silvassa, and Singrauli) are not connected to the corridor and do not serve as its terminal points.
