The correct answer is (d) passing the Stamp Act.
The Stamp Act was one of the first taxes passed by the British parliament on the American colonists. The goal of this law was to generate revenue to help pay off the debt from the French and Indian War. A good amount of colonists felt that this law was unfair, as the law was passed by the British parliament. The British parliament did not possess a representative from the American colonies. This lead to the rallying cry of "no taxation without representation."
To show their disdain for this new law, the colonists boycotted British goods. This boycott was effective, as the British government started to generate less revenue from the colonists. This resulted in the Stamp Act being repealed by the British government.
