retries = 0
while retries < 3:
print(f"retry attempt {retries + 1}")

Correct answer
B. 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. Using a while loop without a clear exit policy is one of the quickest ways to create fragile operational code.
