What term refers to someone or something recognized as an expert in a field?

• A. Credibility
• B. Authority
• C. Trust
• D. Reliable Source

Answer: (B)

Authority is the term used for someone recognized as an expert in a field. This label comes from proven expertise, credentials, and standing within a domain, which gives them influence and the authority to guide opinions on related topics. This differs from credibility, which is about whether the audience finds the source believable, and from trust, a broader sense of reliability or confidence in a person or source. A reliable source describes the quality of the information itself, not the status of the person as an expert. For example, a university climate scientist whose research and credentials establish them as a recognized expert is an authority on climate issues.
