Why was the battle of saratoga a turning point in the war

The battle of Saratoga was a turning point in the Revolutionary War because it convinced foreign powers (France, Spain) that Americans had a shot at winning the war; this in turn prompted these foreign powers to aid the Americans in the war. This is important because the Americans likely would not have won the war had it not been for the aid of the French.

Therefore the correct answer is D.
