What defines Unlawful Entry according to the legal definition?

Unlawful entry is defined by the act of entering a premises or property without the consent or permission of the owner or lawful occupant. This definition aligns with choice C, which highlights the key element of permission. In legal contexts, the concept of unlawful entry encompasses various scenarios where an individual violates the boundaries of another's property without authorization, potentially leading to charges such as trespassing.

The other options do not accurately reflect the legal definition of unlawful entry. Entering a public event without a ticket pertains to issues of access control and ticketing, rather than property rights. Entering a place with approval clearly does not constitute unlawful entry since permission is granted. Lastly, entering during regular business hours might not always imply that one has the right to be there, as it still depends on whether permission has been granted. However, the absence of permission is the defining factor in understanding unlawful entry, thus reinforcing why choice C is the correct answer.
