What legal term refers to an unjustified fault or neglect leading to another's harm?

The correct answer is tort, which refers to a civil wrong that causes harm or loss to another person. In legal terms, a tort is essentially an act or the omission of an act that leads to injury or harm to another individual, for which the injured party may seek legal remedy. The key aspect of a tort is that it involves a fault or neglect that is unjustified, meaning that the responsible party failed to uphold a standard of care or duty owed to the injured party.

In the context of the question, tort encompasses various forms of wrongdoing, including negligence, assault, and fraud, but it specifically denotes the overarching category of civil wrongs. Hence, while negligence is a type of tort that specifically deals with careless actions that lead to harm, referring to it simply as a tort captures the broader implications of legal responsibility for harm caused.

The other terms listed—assault, negligence, and fraud—are specific types of torts or violation categories but do not encompass the full breadth of meaning that “tort” provides, especially in relation to the collective understanding of legal faults leading to harm.
