Which action describes Unauthorized Use of Property in relation to computer or telecommunications?

Unauthorized Use of Property in relation to computer or telecommunications specifically refers to gaining access to a system, network, or data without the explicit consent of the owner. This encompasses a range of activities, such as hacking into a computer system, using someone else's internet connection without permission, or accessing proprietary software without authorization.

The emphasis here is on the lack of consent, which is a critical element in defining unauthorized use. This action is illegal because it violates property rights, including intellectual property rights that are significant in the technology sector. The other options involve actions that include consent or legal rights, which do not fall under the category of unauthorized use. Obtaining consent or sharing property with permission are both legal actions, while selling the property legally assumes rightful ownership, which conflicts with the notion of unauthorized access.
