In criminal law, which elements constitute the essential components of a crime?

• A. Duty and breach
• B. Actus Reus and Mens Rea
• C. Causation and damages
• D. Offer and acceptance

Answer: (B)

Actus reus and mens rea form the bedrock of criminal liability. Actus reus is the actual prohibited conduct or the omission of a duty, and it must be voluntary. Mens rea is the mental state behind the act—intent, knowledge, recklessness, or negligence—depending on the crime. For most offenses, liability arises only when both elements are present, and they must usually coincide so that the wrongful act and the culpable mindset occur together. There are exceptions in strict-liability offenses where mens rea isn’t required, but those are not the norm. Causation and damages relate more to linking the conduct to a result or to civil liability, while offer and acceptance refer to contract formation, not criminal elements.
