Water use efficiency highest for drip irrigation?

Correct option is E

The answer (e) 90-95% is correct because drip irrigation is highly efficient in delivering water directly to the root zone of plants, minimizing water wastage through evaporation or runoff. This method ensures that a significant proportion of the water applied is utilized by the plants, resulting in a water use efficiency of 90-95%. In contrast, traditional irrigation methods, such as surface irrigation, may have lower efficiency due to water losses during distribution.
