According to the second-degree trespass definition, which of the following actions would violate the law?

The definition of second-degree trespass relates to actions involving unlawful entry onto property. Among the options given, entering a property that has "No Trespassing" signs posted clearly violates this definition. These signs are a specific and clear indication from the property owner that entry is prohibited, and disregarding this signage constitutes a direct infringement of the owner’s rights and intentional unlawful entry.

In contrast, leaving a property after being told to do so does not involve unlawful entry, as the individual would be complying with the owner's request. Being invited onto someone else's property implies that permission has been granted, which would not constitute trespass. Remaining on premises where permission was previously granted also does not constitute trespass as long as the individual does not exceed the limits of that permission. All of these scenarios align with consent or compliance, whereas entering a property with posted "No Trespassing" signs directly challenges the owner's wishes and rights, culminating in a clear violation of the law regarding second-degree trespass.
