What does the legal term "perjury" refer to?

The term "perjury" specifically refers to the act of providing false testimony under oath. This typically occurs in legal settings, such as court proceedings or depositions, where individuals are sworn to tell the truth. When a person knowingly makes false statements while under oath, it undermines the legal process and the integrity of the judicial system. The reason "false testimony" is the correct choice is that it precisely encapsulates the essence of perjury, distinguishing it from other forms of dishonesty or misrepresentation that do not involve an oath.

Other options, such as false documentation, false charges, and false representation, refer to different forms of deceit or fabrications that do not specifically relate to the act of lying while testifying. False documentation involves the creation or alteration of documents to mislead, false charges pertain to accusations made without basis, and false representation generally refers to misleading claims made to deceive others in various contexts, including contracts or business dealings.
