What is a legal term for an unlawful intrusion on someone's private life?

The correct answer is a legal term that specifically refers to the act of unlawfully intruding into someone's personal space or private affairs, thereby violating their right to privacy. Invasion of privacy encompasses various acts, including unauthorized surveillance, disclosure of personal information, and physical intrusion into someone's personal life without consent. This legal concept protects individuals from having their private lives scrutinized or exploited without permission, acknowledging the fundamental right to live free from unwarranted interference.

Other options represent different legal issues. Negligence pertains to a failure to exercise reasonable care that results in harm to another person. Defamation involves making false statements that damage another person's reputation. Intentional infliction of emotional distress refers to actions that are so outrageous they cause severe emotional trauma to another person. Each of these terms addresses distinct legal principles and does not directly relate to the infringement of personal privacy as clearly as invasion of privacy does.
