Which of the following does NOT constitute a form of inchoate crime?

Inchoate crimes are offenses that are incomplete or not fully realized, typically involving actions that lead towards a criminal act, but do not culminate in the final crime being carried out. The correct choice reflects an understanding of this legal concept.

Assault, in contrast to the other options listed, is generally recognized as a completed crime in itself. It involves an intentional act that creates a reasonable fear in another person of immediate harmful or offensive contact. Therefore, assault is not merely a step toward committing a crime but is instead an offense that can be prosecuted on its own.

On the other hand, solicitation, conspiracy, and attempt each represent different stages or attempts to commit a crime, thereby fitting into the category of inchoate crimes. Solicitation involves encouraging or requesting someone to commit a crime, conspiracy is an agreement between two or more people to commit a crime, and attempt refers to taking substantial steps toward the commission of a crime that ultimately does not occur. These actions indicate intentions and preparation rather than the enactment of a fully realized criminal act, aligning them with the definition of inchoate crimes.
