Which of the following is an example of mala prohibita?

Mala prohibita refers to actions that are considered crimes because they are prohibited by law, rather than being inherently evil. The term literally means "prohibited wrongs." Gambling is a prime example of mala prohibita, as its legality varies significantly from one jurisdiction to another. In some places, gambling is fully legal and regulated, while in others, it is strictly forbidden. This distinction highlights that it is not the act itself that is universally recognized as immoral or wrong, but rather the fact that certain laws have been established to regulate or prohibit the activity.

In contrast, the other options, such as murder, burglary, and robbery, are considered mala in se, which means they are inherently wrongful acts that are universally recognized as immoral, regardless of law. These acts cause direct harm to individuals or society as a whole and are universally condemned across different cultures and legal systems.
