Under what condition may an agent disclose information about registered sex offenders?

The correct understanding focuses on the ethical and legal responsibility of agents regarding sensitive information, particularly concerning registered sex offenders. Agents are permitted to disclose such information with their client’s permission, as this upholds the principles of trust and consent in the agent-client relationship.

Clients have a right to be informed and involved in the decisions regarding the disclosure of potentially damaging information. While agents are also required to be aware of and comply with legal stipulations surrounding the disclosure of sensitive information, having the client's explicit permission allows for transparency and maintains the integrity of the agent-client connection.

The other scenarios may imply situations where confidentiality and personal privacy could be compromised, which is generally not advisable in real estate practices. Hence, obtaining the client's permission is the most appropriate approach when dealing with sensitive information like the status of registered sex offenders.
