What word describes a person or organization that has power, control, and knowledge in a specific area?

• A. Influence
• B. Authority
• C. Jurisdiction
• D. Power

Answer: (B)

Authority is the term for when someone or an organization has legitimate power to make decisions and guide actions in a particular field, and is trusted for their knowledge or expertise. This combination of formal power, control, and recognized expertise is what makes them an authority in that area. Influence is about shaping opinions, not necessarily possessing formal power or demonstrated expertise. Jurisdiction refers to the scope of power—where or over what it applies—without implying specialized knowledge. Power alone is just the capability to act, not the accepted expertise or legitimate role that comes with authority. So, the best fit for someone with power, control, and knowledge in a specific area is authority.
