The best response to explain the colonists' reactions to the Sugar, Stamp, and Townshend Acts is:
The colonists were most angry about the Stamp and Townshend Acts because those acts generated revenue for the British.
This response captures the sentiment of the colonists' dissatisfaction with British taxation without representation and their resentment towards measures perceived as exploitative. The Stamp Act directly taxed various printed materials, while the Townshend Acts imposed duties on everyday items such as tea, glass, and paper. Both were seen as infringement on colonial autonomy and rights, fueling anger and resistance among the colonists.
