Which of the following is true regarding the sentencing of a conspirator?

The statement concerning a conspirator's cooperation leading to a lighter sentence is accurate because in the context of criminal law, particularly involving conspiracy charges, a defendant's assistance can be influential in how the court imposes a sentence. When a conspirator chooses to cooperate with law enforcement by providing information or testifying against co-conspirators, this cooperation can be highly valued by prosecutors.

As a result, they may file a motion for a reduced sentence based on the defendant's substantial assistance in the investigation or prosecution of others involved in the conspiracy. This principle acknowledges the broader context of criminal procedure in which cooperation is encouraged to dismantle larger criminal enterprises.

The other options do not hold true in the context of conspiracy sentencing. For example, the inability to sentence a conspirator based on their failure to disclose others fails to recognize that a conspirator can still face consequences even without such disclosures. Additionally, not all conspirators receive the same sentence, as sentencing can depend on various factors such as the level of involvement in the conspiracy, prior criminal history, and individual circumstances. Lastly, the actions of a conspirator significantly influence sentencing outcomes, especially when considering their role and any cooperation provided.
