Answer: C

Explanation

Advantages of Drip Irrigation: 1. Maximum use of available water. 2. No water being available to weeds. 3. Maximum crop yield. 4. High efficiency in the use of fertilizers. 5. Less weed growth and restricts population of potential hosts. 6. Low labour and relatively low operation cost. 7. No soil erosion. 8. Improved infiltration in soil of low intake. 9. Ready adjustment to sophisticated automatic control. 10. No runoff of fertilizers into ground water. 11. Less evaporation losses of water as compared to surface irrigation. 12. Improves seed germination. 13. Decreased to tillage operations. Disadvantages of Drip Irrigation: In spite of the fact that drip irrigation has so many potential benefits , they’re a certain limitation also, there are as follow: 1. Sensitivity to clogging 2. Moisture distribution problem 3. Salinity hazards 4. High cost compared to furrow. 5. High skill is required for design, install and operation.
