What does a "subpoena" require from an individual?

A subpoena is a legal document that orders an individual to appear in court or to produce documents, records, or evidence pertinent to an investigation or legal proceeding. Its primary purpose is to compel testimony or the provision of evidence that may be significant to a case. When someone receives a subpoena, they are legally obligated to comply with the request, under the penalty of law. This is essential in ensuring that the judicial process can access necessary information, which helps in examining the facts of a case.

While the other options may involve legal or community obligations, they do not encapsulate the specific function and requirements of a subpoena, which focuses exclusively on compelling participation in a legal context.
