Second most efficient method using rotating sprinkler systems.

• A. Center Pivot Irrigation
• B. Drip Irrigation
• C. Sprinkler Irrigation
• D. Flood Irrigation

Answer: (A)

The main idea here is irrigation efficiency and how water is delivered to crops. Drip irrigation is the most efficient option because it places water directly at the root zone with minimal evaporation, runoff, or deep percolation. Among systems that use rotating sprinklers, center pivot irrigation is a widely used setup that sweeps water over a large field with a controlled, uniform flow from a central point. This rotation helps spread water evenly and reduces the chances of over- or under-watering compared with fixed or non-rotating sprinkler layouts.

Because center pivots still lose some water to wind drift, evaporation from sprays, and some runoff, they don’t reach the high efficiency of drip systems. So, within the category of rotating sprinkler methods, center pivot is typically viewed as the second most efficient choice, sitting above flood irrigation or non-rotating sprinkler configurations.
