- BChennai-Thane
- CKolkata-HajiraCorrect
- DPune-Machilipatnam
Explanation
The correct answer is C because it refers to the old National Highway 6, which stretched approximately 1949 kilometers. This route connected Kolkata in West Bengal to Hajira in Gujarat, passing through states like Odisha, Chhattisgarh, and Maharashtra.
In comparison, the other options are shorter. Agra to Mumbai, the old NH 3, is about 1161 kilometers. Chennai to Thane, the old NH 4, is about 1235 kilometers. Pune to Machilipatnam, the old NH 9, is about 841 kilometers. Therefore, the Kolkata to Hajira route is the longest among the given choices. Under the new numbering system, most of this route is now part of NH 53.
