Multiple choiceHardchapter-2-curatedpremiumfunctionsbatch-helpers
Answer and explanation
Correct answer
A. 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. Capture repeated patterns such as chunking or fee calculation once so operational changes happen in one place.
