def retry(times: int):
def decorate(fn):

return decorateAnswer and explanation
Correct answer
C. 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. Stacking configurable decorators thoughtlessly can hide the true runtime behavior behind layers of indirection.
