Which of the following is NOT a main category of torts?

The correct answer is the category that refers to "contractual torts," which is not recognized as a main category of torts. The three primary categories of torts include intentional torts, negligent torts, and strict liability torts.

Intentional torts occur when a person intentionally acts in a way that causes harm to another, such as assault or defamation. Negligent torts arise when a person's failure to act with reasonable care results in injury to another, exemplified in cases like car accidents. Strict liability torts take place regardless of intent or negligence, where a party is held liable for damages without proof of fault, often seen in cases involving defective products.

On the other hand, "contractual torts" is not a standard classification under tort law. While breaches of contract can lead to litigation, they are typically addressed under contract law rather than tort law. Thus, this option does not align with the main categories of torts commonly recognized in legal studies.
