The correct answer is: B. Hisar.
The Jui Canal Project is a major irrigation project in the Indian state of Haryana. It was primarily designed to irrigate the semi desert areas of Hisar district. The project was started in 1972 and completed in 1982. It has a total length of 190 kilometers and irrigates an area of about 1.25 lakh hectares. The canal is fed by the Sutlej River and its tributaries.
The Jui Canal Project has had a significant impact on the socio-economic development of Hisar district. It has increased agricultural production, improved the irrigation system, and provided employment opportunities to the people of the region.
The other options are incorrect because they are not semi desert areas. Bhiwani, Rohtak, and Panipat are all located in the northern plains of India, which are not semi desert areas.
