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. The model is healthy when the reader can see orders, lines, totals, and validation responsibilities directly in the types.
