What was the outcome the british were looking for from the battle of saratoga?

Explanation:

The answer is a. The expedition, led by Burgoyne, was supposed to rendezvous on the Hudson with another force coming from New York, with the intention of cutting off New England.

The British under General John Burgoyne wanted to isolate New England from the rest of the northern colonies.  They wanted to have full control of the entire Hudson River valley. They also wanted to decrease the number of combatants in the rebel army. The British strategy was to attack from several fronts: from Canada, from Chesapeake and from New York. However, they fell into the error of division of forces.
