选项：

A.The passing away of the client.

B.The involvement of the client's information in unlawful acts.

C.Consent from the client for information disclosure.

解释：

Option C is correct. In accordance with Standard III (E) regarding the Preservation of Confidentiality, it is mandated that all details concerning current, past, or potential clients remain private, except when disclosure is explicitly authorized by the client or prospective client. This standard is upheld to ensure confidentiality is breached only upon receiving explicit permission from the client, thereby safeguarding their privacy and trust.
