Answer: Monitoring online and social media platforms.

**Explanation:** The correct answer is **A** because the Professional Conduct staff utilizes various sources, including monitoring online and social media platforms, to detect any unauthorized disclosure of confidential exam information. - **Option B** is incorrect because Proctor Reports primarily address candidate conduct during the exam and at the exam center, not the disclosure of confidential information. - **Option C** is incorrect because the annual Professional Conduct Statement requires members and candidates to self-disclose matters related to their professional conduct, such as litigation or complaints, but it does not typically include disclosures of confidential exam information.
