Correct Answer:
C. Land fed by rain and torrents
Classifying land based on its irrigation status is vital for accurate revenue assessment, as it directly impacts agricultural productivity and the corresponding tax liability. "Unirrigated land" refers to land that relies solely on natural water sources.
- Land fed by rain and torrents (Correct): This accurately defines unirrigated land as that which depends on natural precipitation and seasonal water flows, without any artificial irrigation systems.
- Lands fed by canal (Incorrect): This describes a form of irrigated land, as canals provide artificial watering.
- Land with artificial watering (Incorrect): This explicitly defines irrigated land, the opposite of unirrigated.
- Desert land only (Incorrect): While desert land is often unirrigated, the definition of unirrigated land is broader, encompassing any land relying solely on natural precipitation, not exclusively deserts.
