Answer 1

Correct answer is (a) alluvial canal

The explanation is: Direct irrigation using a weir or barrage (canal irrigation) is generally preferred in alluvial soil as compared to storage irrigation. Alluvial soil is a fine-grained fertile soil and due to its porosity and texture provides good drainage making it highly productive and suitable for agriculture.
