The Correct Option is B

Solution and Explanation


Step 1: Concept

Emitters (or drippers) are the discharge units used in drip irrigation systems to provide a slow, localized supply of water.

Step 2: Meaning

The defining characteristic of drip irrigation is its very low application rate.

Step 3: Analysis

Standard emitters are designed to release water in drops or tiny streams. While some specialized emitters go lower, the typical commercial range is between 2 and 19 liters per hour (LPH).

Step 4: Conclusion

Range (B) correctly identifies this standard operational discharge.
Final Answer: (B)
