What does a "subpoena" require an individual to do?

A subpoena is a legal document that commands an individual to appear in court or to produce documents, records, or other evidence. When someone receives a subpoena, they are legally obligated to comply with its demands, which can include providing testimony as a witness or supplying relevant documentation pertinent to a case. This mechanism serves to ensure that necessary information is made available to the court or legal parties involved in proceedings.

The options involving defending oneself in court, paying a fine, or formally apologizing are not roles fulfilled by a subpoena. These tasks imply different legal obligations or responses that are not encompassed under the requirements of a subpoena, which primarily focuses on testimony and evidence production.
