Final answer:
The large national debt of Great Britain following the French and Indian War led to the creation of new taxes on the American colonies, contributing to the eventual outbreak of the American Revolution.
Step-by-step explanation:
The large national debt incurred by Great Britain after the French and Indian War in 1762 had significant consequences. One of the direct effects was the need for the British Empire to recuperate the war expenses and manage the national debt. Hence, the correct answer is C) the creation of new taxes on the American colonies. These new taxes included the Stamp Act and the Townshend Acts, which were imposed to raise revenue to pay off the war debt and to maintain British troops that were left in the colonies. These measures were met with resistance by the colonists, thus contributing to the growing tension between the American colonies and Great Britain that eventually led to the American Revolution.
