Correct Answer: Option C — National Highway. National Highway is correct because it is these routes connect capitals, ports, industrial centres and border areas. 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 grade-separated junctions reduce crossing conflicts. It is incorrect here because its separate identifying association is an expressway should not be confused with every divided national highway. • Option B — Golden Quadrilateral: Golden Quadrilateral is it was developed under the National Highways Development Project. 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 East-West axis links Silchar with Porbandar. Exam Takeaway: Connect National Highway with “these routes connect capitals, ports, industrial centres and border areas” and “route numbers identify corridors rather than road quality alone”.
