The correct answer is: C. NH-3
Panipat Expressway is a part of National Highway 3 (NH-3), which is a national highway in India. It is one of the longest national highways in India, connecting Surat in Gujarat to Kolkata in West Bengal. The highway is 1,427 kilometers long and passes through the states of Gujarat, Rajasthan, Madhya Pradesh, Uttar Pradesh, Bihar, Jharkhand, and West Bengal.
NH-3 is a four-lane highway, except for a few stretches in Rajasthan and Madhya Pradesh, where it is a two-lane highway. The highway is well-maintained and is a major artery for transportation in India. It is used by both commercial and passenger vehicles.
The Panipat Expressway is a 40-kilometer-long stretch of NH-3 that connects the cities of Panipat and Karnal in Haryana. The expressway was inaugurated in 2016 and is a part of the Delhi-Mumbai Expressway project. The expressway is a four-lane highway with a speed limit of 120 kilometers per hour. It is a major improvement over the old NH-3, which was a two-lane highway with a speed limit of 80 kilometers per hour.
The Panipat Expressway has reduced travel time between Panipat and Karnal from two hours to one hour. It has also improved connectivity between Delhi and Mumbai. The expressway is a major boost to the economy of the region and has led to the development of new industries and businesses.
The other options are incorrect because they are not parts of NH-3.
