Which of the following actions falls under injury to personal property?

Injury to personal property involves intentional or negligent actions that cause damage to someone else's physical belongings. Option B, using a knife to slash the tires of a car, clearly fits this definition since it is an intentional act that directly harms someone else's property. This action not only results in physical damage to the tires but also provides evidence of malicious intent, which is a critical aspect of property crimes.

The other scenarios can involve varying degrees of intent and impact on the property. For example, while accidentally breaking a neighbor's fence may result in property damage, it lacks the intentional component that characterizes injury to personal property in a criminal context. Similarly, throwing garbage on someone else's lawn, although damaging to property, may not be viewed in the same light as an act of property crime, depending on local ordinances and the nature of the action. Pushing over a recycling bin can also cause damage but often can be seen as a nuisance rather than a direct act of property harm unless it is done in a destructive manner.

Thus, among the options presented, deliberately slashing tires exemplifies the clear and intentional injury to personal property, which is why this action is identified as the correct choice.
