c.They believed their own liberation from slavery was of higher priority than the colonies' independence from Britain.
Explanation:
Many freedmen and slaves sided with the British in the American Revolution because the Continental Army did not officially accept black soldiers, because of that Britain took advantage of this and offered freedom to any black slaves who joined their army.
Because of that, they sided with the British because they believed that their own liberation had a higher priority than the independence from Britain.
We see many slaves and freedmen ally themselves with the British cause during the American war of Independence . The Dunmore's Proclamation of 1775 declared that those slaves who join British army will be freed . The Proclamation made some slaves to join the British army as their own liberation was of higher priority than the colonies' independence from Britain.
