The correct answer is: Canals.
Canals are the largest source of irrigation in Jammu and Kashmir. They account for about 70% of the total irrigation in the state. The other sources of irrigation are wells, tanks, and tubewells.
Canals are artificial waterways that are used to transport water from one place to another. They are usually built to irrigate crops, but they can also be used for other purposes, such as transportation and flood control.
The canals in Jammu and Kashmir are mostly fed by the rivers Chenab, Jhelum, and Ravi. The canals are used to irrigate a variety of crops, including rice, wheat, maize, and sugarcane.
The canals are an important part of the economy of Jammu and Kashmir. They provide water for irrigation, which is essential for the production of crops. The canals also provide employment for a large number of people.
However, the canals are also facing a number of challenges. The water in the canals is often polluted, which can harm the crops that are irrigated with it. The canals are also prone to siltation, which can reduce the amount of water that is available for irrigation.
