d. great britain allowed the colonists to trade with most of europe,

The correct answer is letter C.

Explanation:  Great Britain used the colonies to make profits and mineral and plant resources not available in Europe. Metropolitan exploitation was also very large with respect to the taxes and fees charged by US settlers.

Great Britain decided to raise several taxes and fees, as well as creating new laws that took away the freedom of Americans. These laws include: Tea Law (gave the monopoly of the tea trade to an British trading company), Stamp Law (every product circulating in the colony should have a stamp sold by Britain), Sugar Law (the settlers only could buy sugar from the British Antilles).
