B. America
C. Australia
D. Japan

Answer 1

Drip irrigation is a type of micro-irrigation. Micro-irrigation is an irrigation method with lower pressure and flow than a sprinkler and is also called trickle irrigation.

Complete step by step answer: In the drip irrigation system that is a type of micro-irrigation or trickles irrigation system that can save the water and nutrients as it allows water to drip slowly to the roots and also in the right amounts of the plants and not through above or below the soil surface. This allows drop by drop water supply to the roots and to minimize evaporation. Valves, pipes, tubing, and emitters can be used for the water supply through a drip irrigation system.
The following are some of the advantages of drip irrigation:
Using drip irrigation, the fertilizer and nutrients loss is minimized. If managed correctly the water application management can be increased efficiency and fields with irregular shapes are easily accommodated. Recycled non-potable water can be used, moisture within the root zone can be maintained, and soil type does not play an important role in the frequency of irrigation. Soil erosion and weed growth are decreased, water distribution is highly uninformed and labour costs decrease too. Drip irrigation is now commonly used in farms, greenhouses, and gardens and thus saving water and helpful in the growth of crops like coconut, grapes, tomatoes, etc. China started the use of drip irrigation in ancient times. Israeli engineers commercialized the use of drip irrigation in the 1950s and that allowed the water supply directly through the roots through a perforated tubing on or below the soil and in modern times Israel started using plastic emitters instead of perforators.
Hence, the correct answer is option A.

Note: Germany, China, India, and the USA have also been using drip irrigation with many modifications in modern times. Israel developed and patented the first practical surface drip irrigation emitter.
