Answer : 3. "France lost its Canadian territory"
Explanation :
Answer: C) France lost its Canadian territory Explanation: The Seven Years’ War, a global conflict known in America as the French and Indian War, ends with the signing of the Treaty of Paris by France, Great Britain, and Spain. The Seven Years’ War ended with the signing of the treaties of Hubertusburg and Paris in February 1763. In the Treaty of Paris, France lost all claims to Canada and gave Louisiana to Spain, while Britain received Spanish Florida, Upper Canada, and various French holdings overseas. The treaty ensured the colonial and maritime supremacy of Britain and strengthened the 13 American colonies by removing their European rivals to the north and the south. The British victory in the French and Indian War had a great impact on the British Empire. Firstly, it meant a great expansion of British territorial claims in the New World. But the cost of the war had greatly enlarged Britain's debt.
