The Declaratory Act of 1766 reaffirmed what key principle about British authority?

The Declaratory Act of 1766 reaffirmed the principle that Parliament had the right to tax the colonies in all cases. By enacting this law, the British government asserted its authority over the American colonies following the repeal of the Stamp Act. The act served as a statement that the British Parliament possessed the power to legislate and impose taxes on the colonies, regardless of any local or colonial opposition. This was a pivotal moment in the escalating tensions between Britain and the colonies, as it underscored the idea that Parliament could exercise its sovereignty over colonial affairs completely, which many colonists found unacceptable and contributed to the growing discontent that eventually led to the American Revolution.

The other choices misinterpret the implications of the Declaratory Act; they suggest either a limitation on British authority or a misunderstanding of the tax debate central to colonial grievances at the time.
