B.) They had determination to outlast the British and never give up.

Explanation:

After French assistance helped the Continental Army force the British to surrender at Yorktown, Virginia, in 1781, the Americans had effectively won their independence, though fighting would not formally end until 1783.

The American Revolution—also called the U.S. War of Independence—was the insurrection fought between 1775 and 1783 through which 13 of Great Britain's North American colonies threw off British rule to establish the sovereign United States of America, founded with the Declaration of Independence in 1776. The Revolution also unleashed powerful political, social, and economic forces that would transform the post-Revolution politics and society, including increased participation in politics and governance, the legal institutionalization of religious toleration, and the growth and diffusion of the population. General George Washington led the American army to victory during the Revolutionary War. Despite having little practical experience in managing large, conventional armies, Washington proved to be a capable and resilient leader of the American military forces during the Revolutionary War.
