Drip irrigation is best described as:

Drip irrigation is best described as:

• A. Subsurface irrigation using perforated pipes underground.
• B. Flood irrigation that wets the entire field.
• C. The practice of using small pipes that slowly drip water just above ground to conserve water.
• D. Sprinkler irrigation using overhead nozzles.

Answer: (C)

Drip irrigation is a water-efficient micro-irrigation approach that delivers water directly to the plant root zone through a network of small-diameter tubes and emitters, releasing it slowly in small amounts. This targeted, low-flow delivery minimizes water loss from evaporation and runoff, and keeps moisture where the plant needs it most. The description of using small pipes that slowly drip water just above ground to conserve water captures this idea of slow, localized delivery right at the roots. In contrast, flood irrigation wets the entire field, sprinkler systems spray water from overhead, and subsurface setups involve different underground configurations, so they don’t describe drip irrigation.
