Correct Answer: Option A — North-South and East-West Corridor. North-South and East-West Corridor is correct because it is a national highway development corridor crossing India in two broad axes. North-South and East-West Corridor is also specifically associated with the East-West axis links Silchar with Porbandar. Two additional identifying facts are that North-South and East-West Corridor is the East-West axis links Silchar with Porbandar and North-South and East-West Corridor is associated with Jhansi is an important junction associated with the two axes. Why the other options are incorrect: • Option B — Pradhan Mantri Gram Sadak Yojana: Pradhan Mantri Gram Sadak Yojana is a rural-road programme focused on eligible unconnected habitations.

It is incorrect here because its separate identifying association is these routes connect capitals, ports, industrial centres and border areas. • Option D — Expressway: Expressway is an access-controlled high-speed road corridor. It is incorrect here because its separate identifying association is grade-separated junctions reduce crossing conflicts. Exam Takeaway: Connect North-South and East-West Corridor with “a national highway development corridor crossing India in two broad axes” and “the East-West axis links Silchar with Porbandar”.
