The correct answer is C)They were protesting the Stamp Act.
The Sons of Liberty were a secret organization formed by American colonists who were upset with British policies. One of the main concerns of this group were the taxes implemented by the British government after the French and Indian War. Due to the debt accumulated during this war, the British government implemented a series of taxes on the colonists. The colonists were upset by this, as they had no representatives in the parliament (aka the group making these laws).
This resulted in a series of actions by many American colonists that showed their anger at these taxes. One of these acts was boycotting, which is a refusal to buy a good. In this case, the Sons of Liberty refused to buy paper documents that required a stamp from the British government.
