B. the establishment of unpopular taxation policies.
Of all the choices that seem the most logical. Both the American and French Revolutions were focused on liberty and equality. Both countries were trying to gain freedom. America was trying to gain freedom from the rules and taxes put upon them by Great Britain. Whereas the French wanted to abolish the French monarchy and create a better government in which the people could have more of a say in society. Although the revolutions of both started for very similar reasons, and both countries fought for the same thing, the outcomes of the two were very different.
