Which of the following actions would be classified under property crime?

The action classified under property crime is arson. Property crime refers to crimes that primarily involve the theft or destruction of someone else's property without the use or threat of violence against a person. Arson, in particular, involves deliberately setting fire to property, causing damage or destruction. This aligns with the definition of property crime because it affects material possessions and property rather than individuals.

Robbery, on the other hand, involves taking property from a person through force or threat, which constitutes a violent crime rather than a property crime. Murder is the unlawful killing of another person and is categorized as a violent crime. Assault involves causing or attempting to cause bodily harm to another individual and also falls under violent crimes. Thus, arson distinctly fits the definition of property crime as it focuses on the damage to property itself.
