Answer»

Right choice is (d) Irrigation

The best explanation: Irrigation helps grow agricultural CROPS, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of inadequate RAINFALL. Irrigation also has other uses in CROP production, including frost protection, SUPPRESSING weed growth in grain fields and preventing soil. In contrast, agriculture that relies only on direct rainfall is referred to as rain-fed or dry land farming.
