Answer:
C As the conflict dragged on, however, patriots won the war of propaganda.
Explanation:
In the personal writings of John Adams in 1815, an article was carved out from it which was titled "Loyalists, Fence-sitters, and Patriots."
In it, it was revealed that "Patriots succeeded in convincing others to support the American Revolution."
The sentence from the article that provides the best support for the statement is "As the conflict dragged on, however, patriots won the war of propaganda."
