Keep return values implicit so the script stays short and hope the next engineer infers the rule.Solve the symptom with comments only and avoid changing the code shape around return values.A good return value lets the caller continue the workflow with a clear next piece of information.Delay clarity until production traffic reveals the edge case and then patch it under pressure.

Answer and explanation

Correct answer

C. A good return value lets the caller continue the workflow with a clear next piece of information.

Why

A good return value lets the caller continue the workflow with a clear next piece of information. That is the stronger engineering move because clear return values are a sign that you understand how information flows through the program. Mutating external state for everything makes the control flow harder to test and harder to explain.
