What are the two main components of a crime?

• A. Act/Conduct and Mental State
• B. Duty and Breach
• C. Causation and Harm
• D. Motive and Opportunity

Answer: (A)

The essential idea is that crimes are built from two key parts: the action or conduct itself and the mental state behind it. The action (actus reus) is the voluntary act or omission that breaks the law, something the person did or failed to do under their voluntary control. The mental state (mens rea) is the required mindset at the time of that act—intent, knowledge, recklessness, or negligence—depending on the statute. Both parts must typically be present for liability, so a guilty verdict usually requires a qualifying act plus a culpable state of mind. There are exceptions, like strict liability offenses, where no mental state is required, but those are not the norm. Elements such as causation or harm can matter for specific crimes, and motive or opportunity alone does not establish guilt.
