Answer: C - The summons
Explanation: A summons is a legal written notice issued by the court or an administrative agency, which usually is accompanied by a complaint, notifying the defendant and the court that the complaint has been served on all relevant parties and listing the date of the first court appearance for the lawsuit.
The summons is a document that identifies the court in which the lawsuit will be heard, contains the signature and seal of the clerk and the court, and identifies the parties involved in the lawsuit.
