A. The colonists were upset because Great Britain imposed taxes on the colonists to pay for the French and Indian War.
Step-by-step explanation:
After the French and Indian war, Great Britain started taxing the colonists to help pay for the very expensive war. The British thought this seemed fair, as they were giving the colonists protection against outside forces, but the colonists thought otherwise. The colonists were sick of being taxed without any representation in British Parliament, "taxation without representation." The taxation imposed on the colonists by Great Britain was called the Stamp Act, set on 1765, and put taxes on different paper products such as magazines, legal documents, newspapers, and anything other paper related items.
