A subpoena serves a critical legal function in the investigative process by commanding an individual to appear in court or provide specific evidence relevant to a case. This legal document is an essential tool for obtaining necessary testimony or documentation from witnesses and parties involved in legal proceedings. The enforceability of a subpoena ensures that individuals fulfill their obligation to provide information, which is vital for the proper administration of justice.

In contrast, the other options do not accurately represent the purpose of a subpoena. Requesting legal advice is outside the scope of a subpoena; it is more aligned with attorney-client discussions. A notice of investigation also does not equate to a subpoena's directive nature. While fines for non-compliance may result from failing to adhere to a subpoena, the primary function is not to issue fines but to compel presence or production of evidence. This reinforces the distinct role a subpoena plays in the judicial system.
