Explanation: National Highway 1 (NH 1) is a significant transportation route in India, connecting several important cities and towns. It is one of the longest national highways in the country, stretching from Varanasi in Uttar Pradesh to Haldia in West Bengal. The highway passes through several major cities and towns, including Allahabad, which is also a significant point on this route.
Understanding the route of NH 1 is crucial for students of geography and transportation studies, as well as for those preparing for competitive examinations that include questions on Indian geography and infrastructure. The highway is a vital link in the transportation network of northern India, facilitating the movement of goods and people between the states of Uttar Pradesh and West Bengal.
The correct answer to the question is option D, which states that both options A and B are correct. This is because NH 1 starts from Varanasi in Uttar Pradesh and ends at Haldia in West Bengal, and it also passes through Allahabad, which is another significant city in Uttar Pradesh. Therefore, both segments mentioned in options A and B are valid parts of NH 1.
It is important to note that NH 1 is not a single linear route with a single starting and ending point. Instead, it is a network of roads that connect multiple cities and towns, with Varanasi and Allahabad being two of the major starting points. This complexity can sometimes lead to confusion, especially when students are not familiar with the detailed route of NH 1.
In summary, NH 1 is a crucial highway that connects Varanasi and Haldia, passing through Allahabad, making both options A and B correct. Understanding the route and the cities it connects is essential for comprehending the transportation infrastructure of northern India.
