Drip irrigation is a method of irrigation that delivers water directly to the roots of plants, minimizing water loss through evaporation and runoff. The question asks which country utilizes drip irrigation most efficiently.

Option 1: India. It is true that India is a significant user of drip irrigation due to its large agricultural sector. However, the question is about efficiency, so we cannot definitively say if India uses drip irrigation more efficiently than other countries.

Option 2: Israel. This is the correct answer. Israel is known for its advanced agricultural technologies and efficient use of water resources. Drip irrigation is extensively used in the country to maximize water efficiency and crop productivity.

Option 3: Sri Lanka. There is no specific information provided about Sri Lanka`s use of drip irrigation, so we cannot determine if it is more efficient than other countries.

Option 4: England. Similarly, there is no specific information about England`s usage and efficiency of drip irrigation.
