Based on the historical National Highway numbering system (prior to the renumbering), none of the provided pairs are correctly matched. Old NH 4 connected Mumbai and Chennai, not Chennai and Hyderabad. Old NH 6 connected Hazira (near Surat) and Kolkata, not strictly Mumbai and Kolkata. Old NH 15 connected Pathankot (Punjab) to Samakhiali (Gujarat) and did not pass through Ahmedabad or Jodhpur.
– Old NH 4: Mumbai – Pune – Bangalore – Chennai.
– Old NH 6: Hazira – Dhule – Nagpur – Raipur – Sambalpur – Kolkata.
– Old NH 15: Pathankot – … – Bikaner – … – Samakhiali.
India’s National Highway network has undergone significant renumbering since 2010. Under the new system, NH numbers and routes are entirely different from the old system. For example, the new NH 4 runs from Krishnagiri (TN) to Belagavi (KA). This question likely refers to the old numbering scheme, as the city pairs align more with those routes, albeit incorrectly matched.
