Step 1: Understanding the statements.
Option (A) focuses on the advisor’s personal behaviour and consistency.
Option (B) highlights that advice should be evaluated based on its merit, not on the advisor’s actions.
Step 2: Interpretation.
A person may fail to follow an advice themselves, yet the advice can still be objectively helpful. Wisdom should be judged independently of the person delivering it.
Step 3: Conclusion.
Since the quality of advice is more important than the advisor’s personal conduct, (B) is the more practical and rational choice.
