Explanations:The Golden Quadrilateral is a significant highway network in India that connects four major metropolitan cities: Delhi, Mumbai, Chennai, and Kolkata. This network forms a diamond shape, with each city representing a corner of the quadrilateral. The Golden Quadrilateral was conceived as a part of the National Highways Development Project (NHDP) to improve the connectivity and transportation infrastructure between these major cities.
The cities chosen for the Golden Quadrilateral are not random; they are selected based on their economic importance and population size. Delhi is the capital of India and a major political and economic hub. Mumbai, formerly known as Bombay, is the financial capital of India and a major port city. Chennai, located in the southern part of India, is a significant industrial and cultural center. Kolkata, in the eastern part of India, is a major cultural and economic hub.
The Golden Quadrilateral is not just a network of highways; it is a strategic infrastructure project that aims to boost economic growth and improve the quality of life for millions of people. The network includes four-lane highways that connect these cities, reducing travel time and improving the efficiency of transportation. This network is crucial for the movement of goods and people, contributing significantly to the economic development of the country.
It is important to note that the Golden Quadrilateral is distinct from other highway networks in India, such as the North-South and East-West Corridors. These other networks also form part of the NHDP but have different routes and purposes. The Golden Quadrilateral specifically focuses on connecting the four major metropolitan cities mentioned above.
Understanding the Golden Quadrilateral is essential for students preparing for competitive exams, as it is a topic that often appears in questions related to Indian geography and infrastructure. The correct answer to the question is Option B: Delhi, Mumbai, Chennai, and Kolkata.
