Who defends or pleads a cause on behalf of another?

• A. Advocate
• B. Attorney
• C. Plaintiff
• D. Witness

Answer: (A)

The main idea is who defends or pleads a cause on behalf of another. An advocate is the person whose role is to speak for and argue the client's position in court, representing their interests and making legal arguments to support the case. This title captures the act of advocacy—standing up for the client and presenting evidence and reasoning to persuade the court. While an attorney is a lawyer who can represent clients in various ways, the specific act of pleading and defending a case in court is most precisely described as advocacy. A plaintiff is the party who initiates the lawsuit, not the one who defends it, and a witness is someone who provides testimony rather than arguing the case.
