Which of the following acts is involved in money laundering?

The act of concealing or converting property derived from a crime is central to the definition of money laundering. Money laundering typically involves three key stages: placement, layering, and integration. In this context, the act of concealing or converting property refers to the process of taking illegally obtained funds and making them appear legitimate. This can involve various tactics, such as moving the money through different accounts or disguising its origin through legitimate transactions.

The other options, while they may involve financial activities, do not relate directly to the process of money laundering. Promoting legal investment avenues is an activity focused on encouraging lawful financial behavior. Reporting all incomes accurately pertains to honest financial practices and compliance with tax regulations, which is the opposite of what money laundering aims to achieve. Taking loans from banks is a standard financial practice that does not necessarily involve any illicit activities and does not relate to the concept of laundering money.
