Option d is the correct answer. The Grand Trunk Road, also known as Sarak-e-Azam, Uttarapath, Sarak-e-Sher Shah, and Badshahi Sarak, holds a prominent place as one of the oldest and longest major roads in Asia. With a history dating back at least 2500 years, it has served as a crucial link between Central Asia and the Indian subcontinent. The road stretches approximately 2400 km , connecting Teknaf, Bangladesh, at the Myanmar border, to Kabul, Afghanistan. Along its route, it passes through significant cities such as Chittagong and Dhaka in Bangladesh, Kolkata, Allahabad, Delhi, and Amritsar in India, and Lahore, Rawalpindi, and Peshawar in Pakistan.
