A client is a wholesale auto business that operates as a used car lot.

The correct answer is C. Wires received in large, even dollar amounts are a suspicious behavior, as they may indicate an attempt to avoid reporting thresholds or to conceal the source of funds. Large and round numbers are often used by money launderers to simplify calculations or to avoid arousing suspicion12. The other options are not necessarily suspicious, as they may reflect the normal business operations of a wholesale auto business that ships vehicles internationally. The dock shipping receipts match the vehicles (A), vehicles are regularly shipped internationally (B), and account debits are payable to transport companies (D) are all plausible and legitimate activities for such a business.
