Answer:
Navigation Act
Step-by-step explanation:
The 1651 Navigation Acts were laws that put restrictions on colonial trade by the British Parliament and which were used to increase British power to the detriment of the American colonies.
These laws required all the imports of the colonists to be bought by Britain or resold by them irrespective of its price elsewhere. The British used this to help pay off the debts they got during the French and Indian war.
