Hanumangarh district of Rajasthan was carved out of which district?

The correct answer is C, Sri Ganganagar. Hanumangarh was separated from Sri Ganganagar on 12 July 1994 and became the thirty-first district of Rajasthan; both districts now sit in Bikaner division and both touch Punjab. Option A is wrong because Churu, although a neighbour of Hanumangarh and also in Bikaner division, was not the parent district. Option B is wrong because Bikaner gave no territory to Hanumangarh; it is the headquarters of the division to which Hanumangarh belongs, which is the source of the confusion. Option D is wrong because Jhunjhunu lies in the Shekhawati region and belongs to Jaipur division, well to the south-east of Hanumangarh. The parent district of Karauli, by contrast, was Sawai Madhopur. Hanumangarh is also the district that contains Kalibangan, the Harappan site excavated on the dry bed of the Ghaggar, which is often the real subject of a question that opens with the district name.
