The correct answer is C. Colonist had no voice in Parliament.
After the French and Indian War, the British government sought to raise revenue to pay off war debts and to cover the costs of defending and administering the colonies. The imposition of new taxes, such as the Stamp Act and the Townshend Acts, without colonial representation in Parliament led to widespread protests and the rallying cry of "no taxation without representation." This was a fundamental difference compared to earlier taxes that had been more accepted, as they were often seen as part of British regulation of trade rather than direct taxation without local input.
