Answer :
The word that means "a false, malicious, injurious rumor about a person" is:
1. Slander
Slander is the act of making a false spoken statement damaging to a person's reputation. It involves spreading false information with the intent to harm someone's character. In legal terms, slander is a type of defamation that can lead to serious consequences if proven in court. It's important to differentiate between slander (spoken false statements) and libel (written false statements) when discussing defamation.
Vicissitude, on the other hand, refers to the changes or variations that occur naturally in life, such as ups and downs, fluctuations, or unexpected events. While vicissitude deals with the unpredictability of life, it is not related to spreading false rumors about someone.
