Who is the individual or group that has allegedly done something wrong?

In legal terms, the individual or group that is alleged to have committed a wrong or offense is identified as the defendant. The role of the defendant is central to criminal proceedings, as they are the party accused of violating a law and are entitled to defend themselves against the charges brought forward by the prosecution. The defendant can be an individual, a group, or a corporation that stands accused in a court of law.

In contrast, the prosecutor is the legal representative of the state or the federal government who brings charges against the defendant, the judge presides over the court proceedings and is responsible for ensuring that the trial follows legal protocols, while the witness provides testimony based on their knowledge or observations regarding the case. Thus, the defendant specifically refers to the party facing accusations, making it the correct answer to the question posed.
