Explanations:The Grand Trunk Road is a historical highway that has played a significant role in the transportation and economic development of India. It is one of the oldest and longest roads in the country, with a route that stretches from Amritsar in Punjab to Sonargaon in Bangladesh. The road has a rich history dating back to the Mauryan Empire, and it has been used by various empires and rulers for trade, military movements, and cultural exchanges.
The Grand Trunk Road is not just a transportation route but also a symbol of India's historical and cultural heritage. It has been a vital link between the northern and eastern parts of the country, facilitating the movement of goods, people, and ideas. The road has been maintained and improved over the centuries, with significant contributions from the Mughal Empire and the British colonial period.
Understanding the Grand Trunk Road is important for students preparing for competitive examinations, as it is a part of the general knowledge and geography syllabus. It is often tested in examinations such as the UPSC, SSC, and Bank PO, where candidates are expected to have knowledge of major highways and their historical significance.
It is important to distinguish the Grand Trunk Road from other major highways in India, such as the Golden Quadrilateral. The Golden Quadrilateral is a network of four-lane highways connecting the major metropolitan cities of India, including Delhi, Mumbai, Chennai, and Kolkata. While the Golden Quadrilateral is a modern highway network, the Grand Trunk Road is a historical route with a rich cultural and historical background.
Therefore, the correct answer to the question "The highway from Amritsar to Kolkata is called..." is the Grand Trunk Road. This answer reflects the historical and geographical significance of the route and its role in connecting different parts of India.
