A person or group that can inform the actions and decisions of others.

• A. Authority
• B. Leader
• C. Influence
• D. Advisor

Answer: (C)

Influence is the capacity to shape how others think and act, often through credibility, persuasive communication, or presenting information in a compelling way. When a person or group can inform the actions and decisions of others, they’re exercising influence because their ideas, arguments, or experiences guide choices—even if they don’t hold formal power or a leadership title. This goes beyond merely having authority (formal right to command), being a leader (guiding a group), or acting as an advisor (giving recommendations). Influence can come from expertise, reputation, or persuasive messaging that leads people to reconsider options or adopt new behaviors. In civic life, this is seen when experts, advocates, or media shape public opinion and policy decisions by informing and persuading others.
