Which of the following is an example of an unintentional tort?

Negligence is considered an unintentional tort because it occurs when a person fails to exercise the level of care that a reasonably prudent person would in similar circumstances, leading to harm or injury to another party. This involves a lack of intent to cause harm; instead, the tortfeasor's actions were careless or resulted from a failure to act responsibly, rather than from a deliberate decision to harm someone.

In contrast, options such as assault and fraud involve intentional actions to harm or deceive others, categorizing them as intentional torts. Similarly, intentional infliction of emotional distress is rooted in deliberate actions meant to cause severe emotional anguish to another, which is also classified as an intentional tort. Therefore, negligence uniquely fits the definition of an unintentional tort by emphasizing the absence of intent in causing injury.
