The correct option is Golden Quadrilateral.
Explanation
The Golden Quadrilateral is a major national highway network project in India, managed by the National Highways Authority of India (NHAI). Its primary objective is to connect the four major metropolitan cities of India, forming a quadrilateral shape on the map, to facilitate faster transport and economic growth.
Option Analysis:
- Golden Quadrilateral is Correct: The Golden Quadrilateral connects the four metropolitan cities: Delhi (North), Kolkata (East), Mumbai (West), and Chennai (South).
- East-West Corridor is Incorrect: The East-West Corridor connects Silchar (Assam) in the East to Porbandar (Gujarat) in the West.
- North-South Corridor is Incorrect: The North-South Corridor connects Srinagar (Jammu & Kashmir) in the North to Kanyakumari (Tamil Nadu) in the South.
- Himalayan Expressway System is Incorrect: While there are expressways in the Himalayan region (such as the Zirakpur-Parwanoo stretch), there is no national "Himalayan Expressway System" designated to connect the four major metros.
Key Takeaway:
The Golden Quadrilateral connects Delhi, Mumbai, Chennai, and Kolkata. In contrast, the North-South and East-West Corridors connect the geographical extremities of the country (Srinagar to Kanyakumari and Porbandar to Silchar, respectively).
