What Was One Reason Why the Democratic Convention in 1896

What was one reason why the Democratic convention in 1896 held in Chicago was one of the greatest turning points in American political history?

A) Cleveland emerged as stronger than ever due to his success in quickly responding to and curbing the depression of 1893, setting a precedent for future presidents.
B) The economic issues of everyday people were largely forgotten, as candidates focused solely on how best to support Big Business in their speeches and campaigns to the public.
C) Promises made to African Americans and immigrants for the first time became the central focus of a presidential election, as they were considered the most influential block of voters.
D) The Democratic Party was fractured, and the Silverite, largely rural delegates surprised the party leadership and the "Gold Democrats," or "goldbugs," by capturing control of the convention.
E) For the first time since the Civil War, the Democrats developed a unified platform that would go on to earn them votes in all areas of the country and secure them a presidential victory.
