Assertion (A): The term 'Crime' denotes an unlawful act and this unlawful act is punishable by a state.

Reasoning (R): Crime as a concept is so broad that there is no single, universally accepted definition to it.

Both A and R are correct and R is not the correct explanation of A.

The term 'Crime' denotes an unlawful act and this unlawful act is punishable by a state. Crime as a concept is so broad that there is no single, universally accepted definition to it. But, for the sake of convenience, several countries provide statuary definitions of various kinds of unlawful activities, which can be identified as crimes.
