Final answer:
France allied with the American colonies after the Battle of Saratoga, providing essential military support that helped the colonies defeat Great Britain in the Revolutionary War. Option A.
Step-by-step explanation:
After the Battle of Saratoga, the nation that allied with the American colonies was France. This significant victory for the Americans was a major turning point in the Revolutionary War, convincing France to recognize American independence and enter into a military alliance with the colonies.
The French support included supplies of gunpowder, money, naval forces, and soldiers, among them the notable military leader, the Marquis de Lafayette, who served as an aide-de-camp to General Washington.
The alliance with France was crucial as it provided the colonies with the resources and military strength needed to eventually defeat Great Britain. The infusion of French aid helped shift the balance of power and contributed to the ultimate success of the American Revolution.
So option A is correct answer.
