What is defined as written false information that can damage someone's reputation?

Libel is specifically defined as written false information that can harm an individual's reputation. This type of defamation involves statements that are published in a material form, such as in newspapers, books, or online, which are not true and can cause damage to a person's image or standing in the community. The key aspect of libel is that it is documented, as opposed to slander, which refers to spoken false statements.

In the context of the other options, while defamation is a broader term that encompasses both slander and libel, the question specifically focuses on written false information, making libel the correct and most precise choice. False imprisonment, on the other hand, pertains to unlawfully restraining someone’s freedom of movement, which is unrelated to reputation or defamatory statements.
