The correct answer is: C) Great Britain's navy captured American sailors before the war began.

Because of the conflict between Great Britain and Napoleon Bonaparte's France, both countries tried to block the United States from trading with the other, which damaged and angered Americans deeply. Later on, to make things much worse, the Royal Navy of Great Britain took American sailors into the marine forces without notice to fight on its behalf. Both of these causes ultimately led to President James Madison's Declaration of War upon the British.
