In Road Transport in India, which term combines the facts “route numbers identify corridors rather than road quality alone” and “the Union government is responsible for national-highway development and maintenance arrangements”?

National Highway is also specifically associated with route numbers identify corridors rather than road quality alone. Two additional identifying facts are that National Highway is these routes connect capitals, ports, industrial centres and border areas and National Highway is associated with route numbers identify corridors rather than road quality alone. Why the other options are incorrect: • Option A — Expressway: Expressway is entry and exit are generally limited to designated interchanges. It is incorrect here because its separate identifying association is an expressway should not be confused with every divided national highway. • Option C — Golden Quadrilateral: Golden Quadrilateral is it forms a quadrilateral connecting four major metropolitan regions. It is incorrect here because its separate identifying association is it improves long-distance road connectivity between industrial and urban centres. • Option D — North-South and East-West Corridor: North-South and East-West Corridor is the North-South axis links Srinagar with Kanyakumari.
