Which is a required mental state for criminal liability?

• A. Intentionally
• B. Knowingly
• C. Recklessly
• D. All of the above

Answer: (D)

Criminal liability requires a culpable mental state, but the specific form of that state depends on the statute. The four common forms—intentionally, knowingly, recklessly, and negligently—represent different levels of blameworthiness and can be the required mens rea for different crimes. Because the law assigns different mental states to different offenses, any of these could be the required mindset for a given crime. Therefore, the broad takeaway is that all of the listed forms can be the required mental state, depending on the offense (though there are strict-liability offenses that do not require any mental state at all).
