What was one way that colonial women frequently contributed to political protests during the revolutionary era?
a) by serving as members of colonial assemblies
b) by speaking out publicly against british policy
c) by joining the sons of liberty organization

The Correct answer is option:

D. by participating in anti-British mob activity

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.
