Multiple choiceMediumchapter-13-curatedpremiumservice-designdependency-injection
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. Inject repositories and services at boundary seams so tests and reasoning stay local and explicit.
