Concept:
True learning involves not only understanding concepts but also applying them in practical situations.
Step 1: Levels of learning.
Learning generally progresses through:
• Knowledge.
• Understanding.
• Application.
• Analysis.
• Evaluation.
• Creation.
Step 2: Analyze the situation.
The student can explain the concept, which indicates understanding.
However, inability to apply the concept means the learner has not reached the application stage.
Step 3: Educational implication.
Since application is an important component of meaningful learning, failure to apply knowledge indicates incomplete learning.
The learner requires additional practice and real-life experiences.
Step 4: Conclusion.
The student's learning process is not complete because practical application is missing.
Hence, option (A) is correct.
