Explanations:National Highways in India are a network of major roads that connect important cities and states. They are numbered and play a significant role in the country's transportation infrastructure. The numbering system for National Highways is designed to help identify and locate these major routes easily.
National Highway No 1, also known as the Grand Trunk Road, is one of the oldest and most important highways in India. It connects the national capital, Delhi, to the city of Amritsar in Punjab. The Grand Trunk Road has historical significance and is a vital route for both commercial and personal travel.
Understanding the routes of National Highways is important for various competitive examinations, particularly those related to general knowledge and geography. It is essential to know which highways connect specific cities and states to avoid confusion with other major routes.
For example, National Highway No 2 connects Delhi to Kolkata, and National Highway No 4 connects Delhi to Mumbai. These are also significant highways but are not the same as National Highway No 1. Similarly, there are other highways that connect different parts of the country, but they do not match the criteria of the question.
Therefore, the correct answer is that National Highway No 1 connects Delhi to Amritsar. This route is a crucial part of the national highway system and is well-known for its historical and contemporary importance.
