Use dictionaries when the code benefits from named fields or key-based access that reads like the domain.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 dicts.Keep dicts implicit so the script stays short and hope the next engineer infers the rule.

Answer and explanation

Correct answer

A. Make the rule clearer and easier to explain. Use dictionaries when the code benefits from named fields or key-based access that reads like the domain.

Why

The best review comment anchors the change to readability, correctness, and future maintenance. Blindly passing around giant dictionaries without clarifying their expected keys creates fragile code.
