What Was One of the Reasons Why the American Revolution

What was one of the reasons why the American Revolution was significant to Europe?

A) At the start of the war, most Europeans believed that the Americans would win and, as a result, began to implement American ideals of democracy and representation.
B) Prior to the war, Europeans had begun to experiment with unorthodox modes of warfare, but due to the Americans' successful reliance on traditional warfare, they rethought this shift.
C) The war distracted England from maintaining its other colonies in Asia and Africa to such a degree that during and soon after the war other European powers managed to take control of them.
D) Most European countries such as Spain and the Netherlands sympathized greatly with England in its fight to maintain the colonies and, as a result, consistently fought on England's side.
E) The war proved a world war in that the United States managed to form military alliances with countries that wished to humble Great Britain, including France, Spain, and the Netherlands.
