Answer and explanation

Correct answer

C. Make the rule clearer and easier to explain. Mock or monkeypatch external systems when the goal is to isolate the rule under test from I/O side effects.

Why

The best review comment anchors the change to readability, correctness, and future maintenance. If you mock the behavior you are trying to verify, the test mostly confirms your own setup.
