Explanation

One of the common methods used by money launderers to hide the origin and destination of illicit funds is to create complex corporate structures that obscure the identity of the real owners or controllers of the assets.
Lawyers can facilitate this process by providing legal services such as setting up shell companies, trusts, foundations, or other entities in jurisdictions with weak AML regulations or high secrecy. By doing so, lawyers can help their clients evade taxes, avoid sanctions, conceal criminal activities, or launder money. This is why lawyers are considered high-risk professionals for AML purposes and are subject to due diligence and reporting obligations.

"Lawyers are often used to create complex corporate structures that can be used to hide the beneficial ownership of assets."
* Money Laundering Reporting Officer: The Role Of MLRO, Section "Money Laundering Risks For Lawyers": "Lawyers are at risk of being used by criminals to launder money through various means, such as creating corporate entities, conducting transactions, or providing advice."

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.
