The document naming the official notification to appear in court that includes both summons and subpoena is

• A. Subpoena
• B. Summons
• C. Subpoena & Summons
• D. Court order

Answer: (C)

In legal procedure, a summons is the official notice that a party must respond or appear in court, while a subpoena is the command requiring a person to appear (and sometimes to produce documents) and carry the power to compel attendance. When a single document is used to both notify someone to appear and legally compel that appearance, it is described as a subpoena and summons. This wording explicitly covers both the notification aspect and the enforceable obligation to attend, which is why it’s the best choice. The other options either cover only notification (summons) or only the coercive command (subpoena) or are too broad (court order) to specifically reflect the combination of notice and compulsion.
