Answer:
D. The colonists were threatening stamp agents and boycotting British goods.
Step-by-step explanation:
The stamp act impose a high taxation rate toward various types of paper products that are used by the colonists. Initially, the stamp act was created by the Great Britain to recuperate the loss that the British Government experience during their war against France.
But, they did not expect that the colonists will react by boycotting British Goods.
They realize that the economic damage that is caused by the boycott might be higher than the amount of income that they get from the stamp act. Because of this, they decided to repeal the act.
