Step 1: Understanding the Question:
This question tests knowledge of irrigation methods and their efficiencies.
Step 2: Detailed Explanation:
Drip irrigation is the most efficient irrigation method, with an efficiency of 85-95%.
Sprinkler irrigation has an efficiency of 60-80%.
Flooding and channel irrigation have the lowest efficiencies (40-60%).
Drip irrigation minimizes water loss through evaporation, runoff, and deep percolation.
Thus, drip irrigation has the highest irrigation efficiency.
Step 3: Final Answer:
Thus, drip irrigation has higher irrigation efficiency than others, which corresponds to option (A).
