Where in Haryana is the Indian Institute of Information Technology (IIIT)…

Concept: The Indian Institutes of Information Technology (Public-Private Partnership) Act, 2017 grants each listed IIIT its Institute-of-National-Importance status and identifies it by the city named in its own title (e.g., "IIIT Sonepat") - that named city, not wherever the institute's mentor institute or transit campus happens to sit while it awaits its own facilities, is what a question about an IIIT's location is asking for.

Application: Haryana's institute is titled IIIT Sonepat and appears under that name in the 2017 Act, tying it to Sonepat district. It began classes in 2014-15 under the mentorship of, and physically at, NIT Kurukshetra; from 2018 it moved to Rajiv Gandhi Education City at Kundli (Sonepat district), and since 2022 has run its first three years from a transit campus at Shri Balwant Institute of Technology (SBIT) in the Sonepat-Bahalgarh Industrial Area, with the final year still at the IIT Delhi Technopark facility. Every phase since 2018 has physically sat within Sonepat district, matching its own name and statutory listing.

• Panipat - known for the three historic battles fought there in 1526, 1556, and 1761, and for its handloom and textile industry.

• Ambala - one of Haryana's oldest district headquarters and a major army cantonment town.

• Kurukshetra - associated with Brahma Sarovar and traditionally regarded as the site of the Mahabharata's Kurukshetra War.

Cross-check: The Board of School Education Haryana's (BSEH) official HTET 2023 Computer Science answer key confirms Sonepat as the correct response to this exact item, consistent with the institute's own name/statutory listing and its transit campus at SBIT, Sonepat - matching only Sonepat among the four options.
