Answer:
Right choice:
Destroyed British public support for the war.
Explanation:
General Lord Charles Cornwallis , the British Supreme commander, surrendered to the Continental Army force led by George Washington on October 17, 1781 at Yorktown. The news of the surrender and the great loss of forces in America deeply dissapointed the British public. In March 1782, the British Parliament passed a resolution calling for an end to the war.
