Which of the following notions could provide the basis for a tort?

The notion of a wrong and compensation is fundamental to the concept of a tort. Tort law is primarily concerned with providing remedies to individuals who have suffered harm due to the wrongful acts of others, which could be intentional or negligent. In this context, a "wrong" addresses the actions that cause injury or damage to another person, establishing liability. The element of "compensation" refers to the legal remedy awarded to the injured party for the damages incurred as a result of the wrong. This compensation is intended to restore the injured party, as much as possible, to the position they were in before the wrong occurred.

This understanding of tort law, focusing on wrongs and compensations, is distinct from other legal concepts such as contracts or social agreements, which may not necessarily involve wrongful acts or the necessity for compensatory remedies. While other options mention related concepts, they don't encapsulate the core interplay of wrongful actions leading to the need for compensation as clearly as the notion of a wrong and compensation does.
