A broker must provide disclosure of material issues when using an average if:

This choice implies that mere communication of information to parties is sufficient for disclosure. However, the requirement for disclosure hinges on specific material issues that could impact a transaction, not simply the act of informing others. The presence of an economic interest is a clear material issue that necessitates disclosure.

This option suggests that the broker's performance or teamwork evaluation has a bearing on the need for disclosure. However, the focus of disclosure laws is on the broker's interests and potential conflicts rather than their operational effectiveness. A lack of errors does not exempt the broker from disclosing material issues related to their economic interests.

While familial connections to a property may raise concerns, they do not automatically require disclosure unless they intersect with economic interests. This choice does not address the broker's financial stake or how it might affect the transaction, which is the core reason for disclosure requirements.
