Delay clarity until production traffic reveals the edge case and then patch it under pressure.Solve the symptom with comments only and avoid changing the code shape around invariants in __post_init__.Enforce the basic invariant when the object is created so the rest of the code can trust the instance. Interviewers often respect candidates who push validation to the moment state becomes real.Keep invariants in __post_init__ implicit so the script stays short and hope the next engineer infers the rule.

Answer and explanation

Correct answer

C. Enforce the basic invariant when the object is created so the rest of the code can trust the instance. Interviewers often respect candidates who push validation to the moment state becomes real.
