Type Hints · interview question

A teammate submits shaky protocols code. Which review comment is the strongest?

Choose one answer
Answer and explanation

Correct answer

C. Make the rule clearer and easier to explain. Use protocols when the code depends on a capability or method set rather than on one specific implementation.

Why

The best review comment anchors the change to readability, correctness, and future maintenance. Over-coupling to one concrete class makes testing and substitution harder than necessary.
