In what scenario would one file an "appearance" in court?

Filing an "appearance" in court is a formal act in which a party or their attorney notifies the court of their involvement in a legal proceeding. This is an essential procedure for establishing that the party wishes to be recognized as a participant in the case. By filing an appearance, the individual or their representative is formally acknowledging their presence in the matter at hand, which enables them to receive notifications regarding the case and partake in hearings and other legal processes.

In contrast, submitting evidence for review pertains to providing tangible items or documentation to support a case, but does not involve officially asserting one’s role in the legal proceedings. Contesting a plea bargain refers to challenging or disputing the terms of a negotiated agreement, which is a different process that doesn’t require the act of filing an appearance. Presenting final arguments occurs later in the legal process, when parties summarize their cases before a decision is made, but again, it does not involve the initial formal registration of participation in the case. Thus, "C" correctly identifies the scenario where filing an appearance is necessary.
