Explanation: The Grand Trunk Road is a historical highway in India that connects Amritsar in Punjab to Kolkata in West Bengal. This road is one of the oldest and longest roads in India, with a rich history dating back to the Mughal era. The Grand Trunk Road was originally built by Sher Shah Suri in the 16th century and was later extended and maintained by the British during their rule in India. It has played a significant role in the economic and cultural development of the regions it passes through.
The Grand Trunk Road is not just a transportation route but also a symbol of India's rich history and cultural heritage. It has been a vital link between the north and east of India, facilitating trade, commerce, and cultural exchange. The road has been featured in numerous literary works and is an important part of Indian folklore and history.
In contrast, the Golden Quadrilateral is a different highway project in India that connects four major cities: Delhi, Mumbai, Chennai, and Kolkata. It is a modern highway system designed to improve connectivity and economic growth in these regions. The Golden Quadrilateral does not specifically connect Amritsar to Kolkata, which is why it is not the correct answer in this context.
Expressways are high-speed roads in India, but they are not the specific name of the highway connecting Amritsar to Kolkata. Expressways are a type of road infrastructure that can be part of various highway systems, but they do not refer to the Grand Trunk Road in this context.
Therefore, the correct answer is the Grand Trunk Road, as it is the historical highway that connects Amritsar to Kolkata and is a significant part of India's transportation and cultural history.
