Multiple choiceMediumchapter-4-curatedpremiumserializationjson-parsing
Answer and explanation
Correct answer
C. 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. Parse JSON once, validate the shape, and map it into the structure your own code wants to reason about.
