Correct Answer: Amritsar-Kolkata

Solution : The correct answer is Amritsar-Kolkata.

The Grand Trunk Road connects the two cities of Amritsar and Kolkata in India. With more than 2,500 kilometres, it is among the longest and oldest significant highways. The Mauryan Empire constructed the road in the third century BC, while the Mughal and British Raj empires added to it later. Several important Indian cities, including Delhi, Kanpur, Prayagraj, and Patna, are traversed by the Grand Trunk Road.
