The writers of the Declaration of Independence state that they have a complaint with King George III “for imposing Taxes on us without our Consent.” Which event most directly contributed to this complaint?

C. The Stamp Act of 1765

Explanation:

The French and Indian War made the British spend a lot of money defending its American colonies and they wanted to make the money back somehow so that they could pay off several debts.

This led to them imposing certain laws on the colonies in order to extract this money. One such law was the Stamp Act of 1765. This Act was passed by the English Parliament without regard for the colonists and did not let any of them voice opposition to it.
