In research, 'reliable evidence' means it is?

• A. Credible, accurate, and supported by data or sources.
• B. Biased and unverified.
• C. Anecdotal and personal.
• D. Outdated and irrelevant.

Answer: (A)

Reliable evidence in research means you can trust it because it is credible, accurate, and backed by data or sources that others can verify. Credible means it comes from trustworthy, well-documented origins. Accurate means the information reflects the true facts and measurements. Supported by data or sources means there are data, methods, statistics, or citations you can check and replicate if needed. When evidence meets these conditions, conclusions drawn from it are more trustworthy and less prone to bias. Biased and unverified evidence lacks verification and neutrality; anecdotal and personal evidence relies on individual stories without systematic collection; outdated and irrelevant evidence no longer reflects current facts. So the description that fits best is evidence that is credible, accurate, and backed by data or sources.
