Question Statement:
Read the passage: 'Drip irrigation delivers water directly to the plant root zone via a network of valves, pipes, tubing, and emitters. Unlike conventional flood irrigation, which suffers from massive surface evaporation and deep percolation losses, drip systems maintain high application efficiencies exceeding ninety percent.' The primary thesis is that:
Options:
- (A) Drip irrigation achieves superior water application efficiency by targeting the root zone directly.
- (B) Flood irrigation is universally superior in water-scarce regions.
- (C) Emitters in drip systems never require filtration.
- (D) Drip systems consume more water than furrow irrigation.
