A person commits ____ when he places any item meant to defraud in the postal system to be delivered by USPS.

The correct answer is mail fraud because this term specifically refers to the act of using the postal service to commit fraud. In this context, placing an item in the postal system with the intent to defraud someone—such as sending false documents, checks, or other deceptive items—constitutes a crime under federal law. Mail fraud encompasses activities that involve deceit for the purpose of financial gain and is categorized as a serious offense due to the use of the postal service in facilitating the fraudulent act. This method of committing fraud is particularly noteworthy as it escalates the crime to a federal level, often leading to harsher penalties.

The other options do not fit the scenario as precisely. State Benefits Fraud typically involves fraudulent claims for state assistance or benefits, while Deceptive Fraud is a broader description that lacks specific legal definition or application in the context of using the postal system. Forgery refers specifically to the act of falsifying documents with the intent to deceive but does not encompass the act of sending those documents through the mail as a means to defraud. Therefore, mail fraud is the term that most accurately describes the situation presented in the question.
