Answer and explanation

Correct answer

A. Trace one concrete example, inspect the state transitions, and compare them to the intended rule before rewriting anything.

Why

That approach is reliable because it creates evidence. If you mock the behavior you are trying to verify, the test mostly confirms your own setup.
