The correct answer is A. Yamunanagar.
Jagadhri is a city in the Indian state of Haryana. It is the headquarters of Yamunanagar district. The city is located on the banks of the Yamuna River, about 150 kilometers (93 mi) north of New Delhi. Jagadhri is a major industrial city, with a number of factories producing textiles, chemicals, and engineering goods. The city is also a major railway junction, with trains connecting it to Delhi, Chandigarh, and other major cities in India.
The maintenance of Shatabdi trains is undertaken at the Jagadhri Railway Workshop. The workshop is located in the Jagadhri Cantonment area, about 5 kilometers (3.1 mi) from the city center. The workshop was established in 1965, and it is one of the largest railway workshops in India. The workshop has a capacity to maintain about 100 Shatabdi trains per year.
The other options are incorrect because they are not the districts in which Jagadhri is located. Sirsa is a district in the Indian state of Haryana. Panipat is a district in the Indian state of Haryana. Fatehabad is a district in the Indian state of Haryana.
