Why did many of the nations leader dislike political parties

The Founding Fathers got this one wrong. They were pretty smart guys—they got the whole separation of powers and checks and balances things right—but they completely missed the boat on political parties. They were convinced that political parties (or factions, as they called them) would only destroy representative government and that there should be no place for parties in American democracy. But we have since become dependent on political parties. For the past two centuries, they have played a critical role in both the political and governing processes. 

I would suggest that the answer is likely either B or C. Definitely not A. Have a good day
