Answer : 1. "श्रीगंगानगर"
Explanation :

Sri Ganganagar is a planned city and is the northernmost city of Rajasthan. It is named after Maharaja Shri Ganga Singh Bahadur, Maharaja of Bikaner. For many centuries this area remained barren and unattractive. Only after the arrival of the Ganges Canal in 1927, this ancient land was profoundly transformed. Its sandy barren land was converted into rich agricultural land and various crops were produced and thus a new era of prosperity began in the district. After the construction of Bhakra and Indira Gandhi canals, this process was further intensified and the district thus became the granary of Rajasthan.
