Financial institutions are subject to specific legal and regulatory requirements for record retention to support law enforcement investigations and demonstrate compliance. Core examples of these required records include Currency Transaction Reports (CTRs), Suspicious Activity Reports (SARs) and their supporting documentation, and records of funds transfers (wire transfers), typically for a period of five years. These records are fundamental to creating an audit trail for potentially illicit financial activity.

B. "Special measures" are regulatory actions, not a record type. "Liquid assets" is a balance sheet item, and "national security letters" are a type of information request.

C. "PATRIOT ACT requests" is too general. While CDD information must be retained, this option is less precise and comprehensive than option A.

D. "Market value" is a financial metric, not a specific AML record. "Special measures" are actions taken by regulators, not a standard record kept by an institution.
