Answer:
d protecting rights for voters
Step-by-step explanation:
Not many people had the right to vote in the American colonies, so the protection of rights for voters was not a leading cause of the American Revolution.
The other three statements do refer to specific causes of the revolution: higher taxes, lack of political rights, and violent events such as the Boston Massacre made people furious, and resulted in the unfolding of the events that would give way to the independence of the colonies.
