The correct answer is: B. Tube well
Tube wells occupy the largest share in irrigation in Jharkhand, accounting for 60% of the total irrigated area. Canals account for 20%, tanks and ponds for 10%, and wells for 10%.
Tube wells are a type of irrigation system that uses a pump to draw water from an underground aquifer. They are a popular choice for irrigation in Jharkhand because they are relatively inexpensive to install and operate, and they can be used to irrigate a wide variety of crops.
Canals are artificial waterways that are used to transport water from a source, such as a river or a reservoir, to an irrigation area. Canals are a more expensive option than tube wells, but they can irrigate a larger area.
Tanks and ponds are small bodies of water that are used to store rainwater or water from other sources, such as springs or rivers. They are a less expensive option than canals or tube wells, but they can only irrigate a small area.
Wells are holes that are dug into the ground to reach an underground aquifer. They are a less expensive option than canals, tube wells, or tanks and ponds, but they can only irrigate a small area.
