Answer and explanation
Correct answer
D. 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. Split the code where the responsibilities naturally diverge so navigation and change impact stay readable.
