In criminal law, to convict someone of most offenses, it must be shown that the act (actus reus) was accompanied by the appropriate mental state (mens rea).
- Option A is incorrect because the process used by courts is procedural, not definitional.
- Option C refers to a sentencing outcome, not the legal concept of criminal intent.
- Option D is irrelevant to the meaning of 'mens rea'.
Thus, Option B is correct.
