Multiple choiceMediumchapter-11-curatedpremiumsqljoins
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. Join tables when the use case genuinely needs facts that live in different normalized relationships.
