What does the prosecution do during the trial?

During a trial, the primary role of the prosecution is to present evidence against the defendant to establish their guilt beyond a reasonable doubt. This involves introducing various forms of evidence, such as witness testimonies, documents, and physical evidence, to support the case against the accused. The prosecution aims to convince the jury of the defendant's culpability in relation to the charges brought against them.

Other choices in the question represent different functions that are not part of the prosecution's duties during a trial. Deliberating the verdict is the responsibility of the jury, who considers the presented evidence and makes a decision regarding the defendant's guilt or innocence. Offering a plea deal is a pre-trial process where the prosecution may negotiate with the defendant, but it does not occur during the trial itself. Finally, judging the sentence is the role of the judge after a verdict has been reached, and this function occurs only if the defendant is found guilty, not during the trial process itself. Hence, presenting evidence against the defendant is a crucial aspect of what the prosecution does during the trial.
