The response that most accurately explains why the end of salutary neglect made the American colonies angry is:
The colonies had gotten used to being able to trade with whomever they wanted and paying lower taxes.
This reflects the resentment and frustration of the colonies, as they were used to a degree of autonomy and the ability to engage in trade without heavy oversight or taxation from Britain. The end of salutary neglect meant stricter enforcement of trade regulations and higher taxes, which angered the colonists who had become accustomed to more freedom in their economic activities.
