2. Which irrigation method is most suitable for conserving water in arid regions' \( \begin{array}{ll}0 & \text { A) Flood irrigation } \\ \text { o } & \text { B) Spray irrigation } \\ \text { O Drip irrigation } \\ \text { O } & \text { D) Furrow irrigation }\end{array} \)

The most suitable irrigation method for conserving water in arid regions is: **C) Drip irrigation** ### Explanation: Drip irrigation is highly efficient in water usage because it delivers water directly to the plant roots through a system of tubes, pipes, and emitters. This method minimizes water loss due to evaporation and runoff, making it ideal for arid regions where water conservation is crucial. Unlike other methods: - **A) Flood irrigation** uses large volumes of water, leading to significant wastage. - **B) Spray irrigation** can result in water loss through evaporation and wind drift. - **D) Furrow irrigation** also tends to be less efficient due to runoff and evaporation. **Drip irrigation** ensures that each plant receives the right amount of water directly where it's needed, optimizing water use and promoting healthier plant growth in water-scarce environments.
