The correct answer is B. The colonial victory at Saratoga convinced the French that the colonists could win. The Battle of Saratoga in 1777 was a crucial turning point in the American Revolutionary War. It resulted in a major victory for the American colonists against the British army. The French, who had been considering supporting the colonists, saw this victory as evidence that the colonists had a chance of winning the war. As a result, they decided to formally align themselves with the American cause and provide military and financial assistance.
