Final answer:
William Jennings Bryan served as the prosecutor against John Scopes in the Scopes Monkey Trial, representing the anti-evolution faction in a broader cultural conflict. The correct answer is option: B) Prosecutor against the teaching of evolution.
Step-by-step explanation:
William Jennings Bryan played a significant role in the Scopes Monkey Trial as the chief prosecutor against the teaching of evolution. He was a fundamentalist champion and a three-time presidential candidate who vehemently opposed the secularization of education and the widespread acceptance of Charles Darwin's theory of evolution.
Bryan's role in the trial was not merely legal but also symbolized the broader cultural clash of the era, pitting traditional religious beliefs against emerging modern, secular perspectives. Despite winning the case with John Scopes being found guilty and fined, Bryan's literal interpretation of the Bible was challenged under the skilled examination of defense attorney Clarence Darrow, leading to a perceived public humiliation for Bryan.
