The correct answer is C) colonial protests were harming British trade.
Parliament repealed the stamp act because colonial protests were harming British trade.
The Stamp Act of 1756 was issued by the government of England to impose a tax on every printed material issued in the American colonies. Yes, all the printed material such as newspapers, legal documents, stamps, and magazines. Of course, colonists did not like the idea and were very angry. Taxation like this (the Sugar Act, the Tea Act, the Navigation Acts) were important causes of the Revolutionary War for independence.
