Final answer:
Patrick Henry's ideas in the Virginia Resolves were a direct reaction to the Stamp Act of 1765, which imposed taxes on the colonies without their consent, embodying the principle of 'no taxation without representation'.
Step-by-step explanation:
Patrick Henry's ideas, expressed in the Virginia Resolves, are most directly a reaction to c) the Stamp Act. When the Stamp Act of 1765 was enacted, it led to widespread opposition across the colonies, and iconically to Patrick Henry's speech in the Virginia House of Burgesses where he introduced the Virginia Stamp Act Resolutions. Henry's firebrand speech denounced the Stamp Act in strong language, echoing the sentiment of 'no taxation without representation' and contributing to the foundational ideas that would guide American resistance to British policies. His stance was that Virginians, and by extension all colonists, should be taxed only by their own elected representatives, a principle that was a direct affront to the Stamp Act which imposed taxes without colonial legislative consent.
