The correct answer is D. All of these.
Rohtak, Karnal, and Bhiwani are all districts in the Indian state of Haryana. They are located in the northern part of the state, in the Indo-Gangetic Plain. The climate in this region is semi-arid, with hot summers and cool winters. The average annual rainfall is about 700 mm.
The main source of irrigation in these districts is canal irrigation. However, in recent years, there has been a growing interest in using wind energy for irrigation. Windmills have been installed in several villages in these districts, and they have been found to be a reliable and efficient source of irrigation.
Windmills have several advantages over traditional methods of irrigation. They are a renewable source of energy, and they do not require the use of fossil fuels. They are also relatively low-maintenance, and they can be operated by a small number of people.
Windmills have been shown to be effective in irrigating a variety of crops, including wheat, rice, and sugarcane. They can also be used to pump water for drinking and domestic purposes.
The use of windmills for irrigation is a sustainable and environmentally friendly way to meet the growing demand for water in India.
