B.Grievances of the colonists against Britain

Explanation:

When the Colonists decided to break free of British rule which led to the American Revolutionary War, they did so due to many grievances that they had with the British Government, specifically it's monarch, King George III.

Some of those grievances were;

1. The King dissolved Colonial Legislatures. The Virginia General Assembly and the North Carolina General Assembly were both dissolved for criticizing the practice of taxing the Colonies without their consent.

2. The King took away the colonists' right to a trial by Jury.

3. The British quartered their troops in the houses of colonists after the French and India war to act as a deterrent to attacks.

4. British troops attacked Colonial towns.

There were 23 more grievances making a total of 27 which were made known by the colonists in the Declaration of Independence
