The correct answer is: C. Perennial canals
Perennial canals are canals that are fed by a perennial river, which is a river that flows year-round. Perennial canals are used for irrigation, water supply, and transportation. They are typically built in arid or semi-arid regions where there is a limited amount of surface water.
Permanent canals are canals that are designed to last for a long period of time. They are typically made of concrete or masonry and are lined with an impermeable material to prevent seepage. Permanent canals are used for irrigation, water supply, and transportation.
Ridge canals are canals that are built on top of a ridge or embankment. They are used to collect and transport water from a higher elevation to a lower elevation. Ridge canals are typically used in hilly or mountainous regions.
Inundation canals are canals that are built to control flooding. They are typically built along the banks of rivers or streams and are designed to divert floodwaters away from populated areas. Inundation canals are also used for irrigation and water supply.
