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. Use typed request models so incoming payload shape and validation expectations are obvious at the boundary.
