The statement that most accurately reflects the similarity between trials in Athens and trials in the United States today is: "The accused was considered innocent until proven guilty."
This fundamental principle of the presumption of innocence is a cornerstone of modern legal systems, including that of the United States. The other options do not accurately represent the practices in Athenian trials. For instance, in Athens, jurors were typically male citizens and did not serve based on a panel of 12; rather, juries could be much larger.
