<u> D. by participating in anti-British mob activity </u>
Women in the Colonial Era didn't speak out against the "men" so that one's wrong. They didn't join the "sons of Liberty" organization because it was a Guy's thing the only members were men. So now that it's between these two answers the answer I would go with is D. because when they did mob things they usually disguised themselves which you don't really do that in Assemblies.
I believe your answer would be the App Mountains i remember learning something similar to this in ninth grade but that was in the beginning of it so i might be wrong but i have a pretty good feeling it is :)
