Step 1: Understanding the Question:
This question tests knowledge of irrigation methods and their water use efficiency.
Step 2: Detailed Explanation:
Drip irrigation has the highest water use efficiency (85-95%).
It delivers water directly to the root zone, minimizing losses.
Sprinkler (A): 60-80% efficiency.
Bubbler (C): 80-85% efficiency.
Drumkit (D): Not a standard irrigation method.
Thus, drip irrigation has the highest efficiency.
Step 3: Final Answer:
Thus, the irrigation method with the highest water use efficiency is drip, which corresponds to option (B).
