Which definition best describes criminal trespass in terms of property?

The definition that accurately describes criminal trespass in terms of property is the act of intentionally using property without permission. Criminal trespass fundamentally involves entering or remaining on someone else's property without their consent. This concept not only encompasses unauthorized entry but also includes situations where an individual uses the property without the owner's approval.

Option C focuses on the element of intent and the absence of permission, which are critical components of criminal trespass. While damaging property might be a related offense, criminal trespass itself is primarily concerned with unauthorized use or presence on the property rather than inflicting any physical harm or damage.

The other choices do not capture the essence of criminal trespass effectively. Unauthorized entry may refer to a single act of entry, but it lacks the broader context of ongoing unauthorized use. The act of entering with the intent to commit a felony pertains more to burglary than to trespass. Lastly, intentionally damaging property relates to vandalism or destruction, which, while it can occur during a trespass, does not define the act of trespassing itself.
