The correct option is B

The battle of Saratoga was one of the most important wars fought during the course of the war of independence of the United States. Its outcome contributed, to a large extent, to deciding the final outcome of the contest in favor of the continental army. This battle took place between September 19 and October 17, 1777 in Saratoga, a region located between Boston and the Great Lakes area, in the vicinity of the Hudson River. The victory strengthened the possibility of triumph of the citizen militias over a line army, which precipitated the support of France (1778) and the Spanish Empire (1779) to the American independence cause.
