An executive forwards a screenshot of one clearly wrong answer from the internal knowledge assistant and asks for it to be fixed today. Which two responses are most appropriate? Select two.

Answer: C and D — Check the metrics and sampled quality for that topic to see whether the error is isolated or part of a trend / Reproduce the case, triage its root cause, and add it to the eval set so that the fix is regression-tested

(c) and (d) are right: check whether the anecdote reflects a trend (or a gap in sampling), and route the case through triage and the eval set so the fix is real and stays fixed; then report back. (a) is a one-off patch with no regression run that can break other cases. (b) is an expensive reaction that may not address the root cause, which is often retrieval or source content.
