Which district of Rajasthan was formed on 26 January 2008?

The correct answer is D, Pratapgarh. Pratapgarh was formed on 26 January 2008 out of parts of Chittorgarh, Udaipur and Banswara, and was the thirty-third district of the state; it remained the newest district until the reorganisation of 2023. Option A is wrong because Karauli was carved out of Sawai Madhopur on 19 July 1997 and was the thirty-second district. Option B is wrong because Hanumangarh was carved out of Sri Ganganagar on 12 July 1994 and was the thirty-first district. Option C is wrong because Rajsamand was separated from Udaipur on 10 April 1991, on the same day as Baran and Dausa, taking the state from twenty-seven districts to thirty. Pratapgarh belongs to Udaipur division. A useful memory hook is that Pratapgarh was notified on Republic Day, and that it is the only district of Rajasthan formed out of parts of three parent districts at once.
