Which of the following wild life sanctuaries is located in Shivalik heights?

Haryana's wildlife sanctuaries lie across different physiographic zones. Many of the state's lower-lying sanctuaries are wetland or lake habitats in the Punjab Plains, developed for waterfowl; a narrow belt in the northeast, running through Panchkula and Yamunanagar districts, extends into the Shivalik (Siwalik) range -- the outermost, youngest foothills of the Himalayas.

Checking each option against this: Khol Hi-Raitan Sanctuary lies in Panchkula district, within the Morni Hills, which are part of the Shivalik range -- so it satisfies the condition in the question.

• Khaparwas Sanctuary -- Jhajjar district; a lake/wetland habitat in the Punjab Plains, not the Shivalik hills.

• Bhindawas Sanctuary -- Jhajjar district; a man-made freshwater wetland/lake in the Punjab Plains, not the Shivalik hills.

• Nahar Sanctuary -- Rewari district; classified in the Punjab Plains (former pastureland), not the Shivalik or Aravalli hills.

Since only one of the four sanctuaries falls within the Shivalik range, Khol Hi-Raitan Sanctuary is the answer.
