Multiple choiceEasychapter-3-curatedpremiumcore-collectionsdicts
Answer and explanation
Correct answer
B. When the rule is no longer easy to trace, explain, or change without breaking nearby behavior.
Why
A refactor is justified when the code stops communicating its intent. Use dictionaries when the code benefits from named fields or key-based access that reads like the domain.
